Ah, that’s what you’re getting at. A person’s vocation (whether it be marriage, the priesthood, lay celibacy, or the religious life) is pretty much predetermined by God. It is the decision of the individual to follow it or not.
In the case of gays and lesbians, their vocation is celibacy.
Their vocation is not having sex with people of the same gender.
The idea that our lives shouldn’t be difficult and sometimes painful is not one that I subscribe to, however, and I’m afraid that while I have sympathy for people who suffer this way, I don’t think remaining celibate is the end of the world.
That’s pure hatred.
