I think I consider it irrational, in that I think prejudice against ape/lizard people is irrational, and I would totally call it that for males, too (in fact, I was watching the whole thing, thinking, "Normally, this would be a bunch of men being jerks and saying that insulting nonsense.")

I do think there's a slightly more... well, it's the whole mothers and sisters and familial bonds thing, that felt less 'male'.

But the emotional connections are NOT the irrational part of things.
