Those who take absolutist statements literally need to remember that "only a Sith deals in absolutes." I submit that it is not reasonable to take such a statement literally. I also submit that my statement was still accurate: it is not reasonable to take Aquinas' sexist statements as true, and thus someone who does is being unreasonable, and is not a reasonable person in that regard. Further, my statement STILL does not say that no one believes it, but that no one reasonable does. There's a vast difference. But I can't stop you if you insist on making a villainous meaning out of it, much like the Harvard president. At least I'm in good company.
In short, we're not in disagreement about there still being sexism in the world. I concur. I believe that those who are sexist are unreasonable. I also believe that you paint a much bleaker picture than it is.
Now, as for prostitution, Gopher and Archon would be wrong on this one. There are often not opportunities for women who work in porn or as prostitutes. Many of these women are forced into this situation. And many many of those who "chose" it, even who claim to enjoy it, can be demonstrated to have been forced/manipulated into it or are only doing it to feed certain addictions they'd just as soon be without.
However, I think if you take the percentage of women doing those things you'd find it rather small (granted, any is too mcuh, but my point is not to discuss the morality of these aspects, but to point out that prostitution and porn is NOT always, or even frequently, a choice -- go attend some psycholocy/sociology lectures on the subject before you comment further, because the experts disagree with you). And the percentage of men who are doing this forcing is rather small. The percentage of people who think this behavior is reasonable or right is not great. Yes, there's sexism. You run into it every day. but that behavior is not reasonable. and nor do I know anyone who uses Aquinas to establish their bigoted views.
