In my world, sexuality, religion and a few other select issues are highly personal. They are best resolved, discussed and dealt with among family, close friends, and clergy.
If homosexuals had the same attitude and didn't shove the gay agenda down everyone's throats via judicial fiat, bias laws, school indoctrination, gay pride parades, and so on, no one would know or care what they do.
Unfortunately, they have no wish to keep it private. Maybe some do, but enough don't so that the activists and their supporters are rapidly trying to change the world into one that suits them.
