"Life" Protests
I always thought the pro-life protests in which women taped their mouths shut and wrote "life" over them were a little odd. I'm glad I'm not the only one:

Freethinkers and Free Will
I recently stumbled upon an opinion in the Des Moines register that I found interesting. The author believes that atheists and agnostics cannot call themselves freethinkers. He has two arguments. The first relies on the fact that the first freethinkers were deists and unitarians. Um, so? Freethought is a manner of belief formation - which beliefs get formed are irrelevant to whether or not you are practicing freethinking. But this plea to history is not the author's main argument. His main argument is the following:
If everything transcendent is mere superstition, then your every thought is determined in minutest detail by a chain of natural cause and effect stretching back to (and beyond) the Big Bang. You can't be an atheist and call yourself a freethinker.
You are obliged to believe that you are nothing more than a machine, freewill is illusion, and your mind is a mere epiphenomenon, a dead-end byproduct of the chain of cause and effect.
Before I get started on this, two side notes - first, being an atheist, even one who embraces philosophical materialism, does not commit you to the claim that your mind is "a mere epiphenomenon". I wonder if the author even knows what an epiphenomenon is. Most (philosophically educated) philosophical materialists believe that "mind" is a description of certain functional system and that in our case this functional system just happens to be instantiated in a physical substrate - the brain. An epiphenomenon is a causally inert emanation of a system. Totally different.
Second, the causal chain does not extend beyond the big bang. Cause and effect are temporally bound - you can't have cause and effect absent of time. Time was a product of the big bang. So, no cause and effect "beyond" the big bang. (I understand that it is difficult to talk about the big bang using a language that is laced with temporal and causal connotations. My use of "product" with respect to the relation between time and the big bang is suspect. But at least get the facts straight)
Side notes aside, in a way, the author is correct that atheists and agnostics cannot be freethinkers, but not in the way he thinks. The thinking of most atheists and agnostics is not free - it is bound by the contraints of reason. This is obviously a constraint the author has not placed on his own thoughts, since his arguments are frought with fallacies (as was the one I just made. But that was for rhetorical force.) First, "freethinker" does not mean "possessed of libertarian free will". It means "one who forms beliefs on the basis of science and reason as opposed to dogma". Since the two terms are not synonymous, the author is equivocating. Even if he were correct that atheists cannot believe in libertarian free will, that doesn't mean that they can't be freethinkers.
Despite the fact that his argument as a whole falls flat on its fallacious face, I'd like to address his claims about atheists and free will. It is a common misconception about atheism that it automatically commits you to "hard determinism" - the idea that the author describes as our being "a dead end by-product of the chain of cause and effect" (although he's wrong about the dead end bit. Your thoughts, etc, are links in the chain). This is false for two reasons.
First, an atheist need not be a philosophical materialist. Since atheism is nothing more than a lack of belief in a deity, it is entirely possible for an individual to be an atheist and still hold that there is something above the physical where libertarian free will resides.
Second, even for those of us who are philosophical materialists, it is possible to believe in libertarian free will. Developments in quantum physics have demonstrated that there is causal indeterminacy at the quantum level. If you believe that the causal indeterminacy at the quantum level translates to indeterminacy at the macro level (say, indeterminacy in which way the neurons in your head move), then you've got yourself some libertarian free will.
So, the author is wrong on two counts. Even if you don't believe in free will, you can still be a freethinker, and it is also entirely possible to be an atheist and believe that we have libertarian free will. I personally don't believe in libertarian free will, but that's just me. Other atheists are free to accept it.

Bishops on Reducing Abortions
According to some Catholic Bishops, abortion rates cannot be reduced unless Roe v. Wade is overturned.
You might think that makes sense, but it's false. Guttmacher's statistics indicate that there is no correlation (much less causal relationship) between the legality of abortion and the number of abortions that occur in a country:
while it may seem paradoxical, a country's abortion rate is not closely correlated with whether abortion is legal there. For example, abortion levels are quite high in Latin American countries, where abortion is highly restricted. (In fact, 20 million of the 46 million abortions performed annually worldwide occur in countries with highly restrictive abortion laws.) At the same time, abortion rates are quite low throughout Western Europe, where the procedure is legal and widely available. Also, Eastern and Western Europe have the world's highest and lowest abortion rates, respectively, yet abortion is generally legal throughout the Continent.
In fact, if you put a little thought into it, you realize that the best way to reduce the number of abortions is to prevent what causes them - unwanted pregnancies. How do you prevent unwanted pregnancies? Birth control! And the data bears this out:
Abortion levels are high in countries where the desire for small families is strong but contraceptive use is low or ineffective. For example, in most of Eastern Europe and the former Soviet republics, where desired family size has been small for many years, modern contraceptive methods were not generally available until recently. As a result, women relied on abortion—which was legal, safe and easily accessible—to regulate births. However, as contraceptives have become much easier to obtain in recent years, the situation has begun to change rapidly, and abortion rates in some of these countries fell by as much as 50% between 1990 and 1996.
Of course, the Bishops can't tell you that greater access to contraception will lower the abortion rate in the U.S. because they oppose contraception just as vehemently as they oppose abortion. When will these people let their conclusions be informed by the data? When will they assess the facts on the basis of evidence rather than their preconceived dogma?
Oh wait... they're bishops. Nevermind.

The "Real" America
After the recent comments made by Sarah Palin, Nancy Pfotenhauer, and Michelle Bachmann, I was ready to write out a long post about how this divisive understanding of our country was horribly misguided, insulting, and dangerous to the nation.
Thankfully, I didn't have to. Jon Stewart did it for me.
