In line with the results of the poll here, a thread for discussing politics. Incidentally, folks, I think downvoting the option you disagree with in a poll is generally considered poor form.
1.) Top-level comments should introduce arguments; responses should be responses to those arguments.
2.) Upvote and downvote based on whether or not you find an argument convincing in the context in which it was raised. This means if it's a good argument against the argument it is responding to, not whether or not there's a good/obvious counterargument to it; if you have a good counterargument, raise it. If it's a convincing argument, and the counterargument is also convincing, upvote both. If both arguments are unconvincing, downvote both.
3.) A single argument per comment would be ideal; as MixedNuts points out here, it's otherwise hard to distinguish between one good and one bad argument, which makes the upvoting/downvoting difficult to evaluate.
4.) In general try to avoid color politics; try to discuss political issues, rather than political parties, wherever possible.
If anybody thinks the rules should be dropped here, now that we're no longer conducting a test - I already dropped the upvoting/downvoting limits I tried, unsuccessfully, to put in - let me know. The first rule is the only one I think is strictly necessary.
Debiasing attempt: If you haven't yet read Politics is the Mindkiller, you should.
I think nearly all the responses to this question miss the point. your points (both the original comment and the responses) use a "less wrong" type definition of rationality/pragmatism/reasonableness, none of which apply to the many religious pro-lifers.
When looking at abortion from a religious perspective, and not a legal or "less wrong" rationality perspective, being pro-life is absolutely consistent with not wanting people to use birth control. procreation, all relevant acts and the results relating thereto, are sacred and should not be messed with. Simple - that's all there is to it. Though i personally do not believe in these, it strikes me as a reasonable and principled way of looking at the issue (e.g., most believe life is sacred, most pro-choicers dont like abortion, etc.). The idea of "cutting your losses" and being pragmatic, from a religious viewpoint, is actually quite ridiculous. Losing the issue is 100% better than being pragmatic precisely because it allows the pro-lifer to live their life in a manner that is consistent with their guidepost -- religion. Religion serves as their moral compass. In many ways, these religious morals are consistent with the legal and pragmatic perspectives the less wrong community generally supports. When they diverge, the less wrong community looks to "rationality," the religious look to their religion. I believe a vast majority of religious folks are "subjectively rational." Objective rationality is rationality that can be proven correct. Subjective rationality is rationality that cannot be proven wrong. So long as you cannot prove there is no god (which you can't, sorry!), religious arguments, particularly ones that at its core are trying to preserve life (and embryos that result in life) will have my vote as subjectively rational. I note that most countries, paricularly the united states, were formed and flourished with religious laws carrying the day, at least from moral and personal perspective.
This is not to say your arguments are "wrong" in the abstract, frankly, its irrelevant. In a social environment/community, being "right" is only as important as the number of people that agree with you. We live in a world where a significant portion of the population is pro-life/etc. To me, trying to judge their perspectives within a framework that on its face is inapplicable sounds like a waste. Seems more important to understand the varying models these people are using, since we're forced to deal with them irrespective of having the "correct" (pragmatic/rational) viewpoint.
