Well, maybe not eliminate, but a lot of gay lefties think that homosexual sex is preferable because they do not reproduce. They think of heterosexuals as a form of pollution to be tolerated on a limited basis.
I used to have a leftist radical lesbian friend who once told me that “men should be farmed for their sperm and then exterminated”.
That is a direct quote from her.
Heterosexuals are viewed as a threat by homosexuals because we see and speak out about their perversion. We don’t want our children and grandchildren to be indoctrinated and molested by them.
They want us GONE.
