He's not afraid of being disowned because of an inheritance. They will probably not pass anything monetarily down to us after death. He does value their opinions... somewhat. I think in his mind though, they would disown him because "that's just how they were raised and they don't know any better." Because I have no doubt that any of his peers have anything against being gay, like I said, a lot of people in my generation encourage it.
So, to a lot of people in this day, the gay rights movement is simply another version of the black rights movement. And that anyone who still thinks that being gay is wrong is just living in the past. And that one day years from now people will look back and say "Wow, people really thought that about gays and they didn't let them get married?" Kind of like people do now with race. It is very common for Christians around my age and younger to think that you can be practicing unrepenting gay and still be a Christian. Some even think that homosexuality isn't a sin at all.
This is NOT what I believe but what a lot of non-Christians and lukewarm Christians think about being gay and the whole gay rights movement.
I guess this is just an explanation of why it probably won't matter what I or anyone else says to him, that he will just write me off as living in the past and being close minded.
