Straights that are pro gay are probably opposed to any limits on their own sexuality.
They’re probably pro abortion, pro divorce, pro cohabitation, pro extramarital sex, etc.
It just follows from this. And if they feel inclined to act on same sex feelings, they don’t feel the inhibiting influence of traditional morality here, either. I think that explains why it seems there’s more gay people these days.
What a load. Straight people who support gays just might love their family member WHO WAS BORN THAT WAY.
