Until recently gays were pressed to "act straight" and so far as to marry and have children.
If it becomes so acceptable to fully live the homosexual lifestyle that they NEVER get married or have children THEN in a few generations homosexuality will fade away. That is only if it is genetic.
So basically...
1. If homosexuality is a choice, and there is no genetic component, there is no basis for "gay rights."
or
2. If homosexuality is a genetic "defect," letting it be fully expressed will eventually lead to it fading away.
Sounds like a "win-win" proposition to me...
If they keep it a private matter as they keep screaming that it is (all the while conducting those silly gay pride parades), then there's no problem. When they demand that I 'accept' it as normal, they they have a problem.
