I do see the truth in that statement. I've seen MANY "cat-people". Sad to say, I've experienced a few. They're commonly called "takers". C'mon, we've all experienced this. I think that the potentially offensive part is the purportation that that can only apply to women.
I don't know who Schopenhauer is, but I'm GUESSING that he hails from an earlier era. There really aren't that many traditional~ *man supports, woman stays home with kids* relationships anymore.
