"In my experience, gay people have been X."
"In my experience, Betas have been X."

Honestly, how is it helpful to fight stereotypes with stereotypes? This is so idiotic that I wonder if people still have functioning brains.

The entire point of stereotypes is that it's based on your own limited observations, or lack thereof. It cannot, for instance, imagine that gay people could also be X, Y, Z... Because that's sort of an abstract imagination or abstract logical rules that's not based on any observations.
