Well, we all have our reasons for doing this or that, even if we haven't consciously made the choice.
I have deep-seated reasons for my behavior in those topics and I don't know if I could articulate them as logical argument, but I do know that they have something to do with being female. Other women feel differently about the same topics, so there's lots more at work, but I think that's a prerequisite.
I assume their reasons had something to do with being male.
