When I was a young man, there were homos around as well.
But they were never interested in competing in sports at all, much less with the girls.
They were just interested in taking it in the ass or shoving gerbils where the sun does not shine. They figured that was enough to honk off us "straight arrows"
But in recent years, Normative people have become more tolerant of homosexuality.
The result has been they start engaging in fake societal institutions- like Gay Marriage- and even want to compete in girls sports.
This would have never come down, and homos would have never thought of this, if more people had got properly cheesed off at homo adoptions and unions.
