With race, we aren't talking about biological factors.
With gender we are, so it's difficult to draw the line.
Some women are turned on by men who exhibit these characteristics.
Do we blame patriarchy or her biology?
I know many women like masculinity because of their biology,
but it's difficult to draw the line on where her determination of what constitutes masculinity
is stemming from.
What turns you on or moves you isn't always (I'd be willing to say it usually isn't) determined
by culture... which may cause you to fight it, but it doesn't change it.

So the comparison to racial discussions doesn't hold up here, and only serves
to shut down the conversation, in this particular instance.

If we were talking about how ppl are sexist without realizing it just like they can be
racist without realizing it, that would be a point of intersectionality. We just happen
to be a point that doesn't intersect.
