Of course they are. The more they get to know their classmates the less ignorant they become and hence the less weird behaviors they exhibit.
Yes, we’ve always known that men who associate more regularly with women than other men, act more like women.
Are there rules for how genders are supposed to act?
There are over 200 years of records and observation.
We can make models of how the average man or woman tends to behave in a given region.
For example. We know that men are a lot more likely to study to become mechanics than women. That’s not a rule that women can’t. But it’s a statistic that they often don’t
What’s the statistics say about which ear is good for an earring?
Depends entierly on the region. Different places have different customs regarding the stereotype for which ear is the “good ear”.
What if I don’t follow the rules, but I’m straight?
I never said it’s a rule. I said it’s a stereotype. I dunno. Someone might assume you’re gay.
Assuming is pretty rude. I need an indicator over my head. Something to let them know.
