All things classified as moral or immoral, are but points on a scale, that the majority is willing to tolerate.
I bet you have limits Ruffy. In old Greece, the old men used to like young slave boys. So, by your own example of acceptance through historical reference. You must approve of old men, sexually abusing teenage young slaves? Or, are you going to claim you now don't accept everything. And, don't tell me that it's somehow different. The age of 18 is just a number pulled out of some psychologist's research notes. Slavery is still practiced in many parts of the world. If their going to schools teaching young men to accept homosexuality, you can't speak to all their motivations for doing so.
Anyway, I don't much care what gay people do. I just wish they'd quit pushing it down everyone else's throat, and quit preaching the crap to kids. And, their constantly trying to get themselves classified as some sort of disadvantaged minority. So,keep it in the closet.
