I also don't believe it's sexist to point out differences between the genders. Women are more adaptable than men to changes in social structure. That's a fact. Acknowledging this fact is not sexist.
It really annoys me how people want to label everything as sexist, racist, or whatever just because you didn't take extra care to spare someone's feelings. But I'm not a feminized male, so that's probably just a problem with me. LOL
