I'm with you, especially because people have been saying this for over 50 years now. Sadly, as I get older it seems clearer to me that while power is bound to shift, injustice is not going to be eradicated any time soon.
I'm surprised about the poll you mention though. I do always think of young people as more open and accepting on the LGBT front. It seems like there are more parents open to raising children with less rigid gender identities than when I was a kid. But what do I know? I'm don't know many teenagers and I'm living in a strange little corner of the world.
