What you're seeing is a snapshot of certain views that exist out there in society. I think it is better to face this stuff head on than to pretend it doesn't exist.
It is exactly the kinds of views that we're seeing from SetiAlpha6 that are having real-world effects like the recent anti-abortion laws in Alabama and elsewhere. I think it is important that such views are confronted rather than silenced.
This thread is now in the Religion subforum, because it has become clear that SetiAlpha6's motivations, at least on the superficial level, are religious. That is, he chooses to excuse himself using his religion. I think it is important that people are not unnecessarily shielded from seeing how these people work, and that they are given an opportunity to interrogate the smokescreen. Inevitably, a religious discussion of this nature is going to involve some proselytising or preaching. The religion, after all, is the excuse given for the odious position. Lacking a rational position on the matter, the religious advocate has only his religious excuses to fall back on.
Fundamentalist religion is often patriarchal. It confines its followers - often to their own detriment - to live in a world in which women are not allowed to fully express themselves, and in which their choices are limited. Some men think that is the way things ought to be, of course, and that may be one reason they are attracted the religion in the first place. Understand that these people are deeply indoctrinated and have vested interests. Partriarchal views are likely unavoidable from certain brands of devout fundamentalist. If we are to talk to them in an effort to understand, and perhaps ultimately to change their minds, we can't really avoid exposure to some of that stuff, odious as it is.
In a discussion about abortion like this one, it is also all but inevitable that some of the men who are participating will be sexist, and that their views will be grounded in their sexism. It is all but impossible for these men to articulate their views without the sexism seeping through.
In summary, you see why this thread has been allowed to continue. It's a chain of links. The view on abortion flows from the sexism, which is tied to the patriarchy, which is tied to the fundamentalist religion. These people can't discuss the one without the other becoming obvious. The only alternative to discussion is to silence the voices of these men by preventing them from posting at all on the topic. Some (Tiassa, for instance) would certainly prefer that. I disagree that this is the best approach to addressing these issues in society.
Regarding this forum, I made the point to Tiassa some time ago that I believe our more balanced members are mature enough and adult enough to handle being exposed to these kinds of views. There is always the option not to read. It should be quite clear that the views of these men do not represent the views of the sciforums community at large, or its administrators or its moderators.
I agree with most everything you've posted here, James...except, the second sentence of your OP. I'm not suggesting that we ''pretend'' that this rhetoric doesn't exist, but to let someone evangelize, preach, post sexist remarks for 50+ pages...it appears like we're encouraging it to continue. In other words, when a thread starts to resemble a personal blog for a religious member to witness their faith, it can create a slippery slope.
