Same-sex marriage. This has to be #1, because even though I came out in 1963, I never would have imagined that SSM would be legal anywhere in my lifetime. The concept was so alien as to be unthinkable. And gay rights in general. In the '60s you could get arrested, or worse, just being in a gay bar. The vice squad would come in, arrest people, rough them up, take them to jail, print their names and addresses in the paper, and sometimes beat the crap out of them . . . or worse. People lost their families, their jobs, and sometimes their lives, just for being in a bar.
End of the Cold War. Yes, those ICBMs are no longer hanging over our heads 24/7. No more air-raid shelters, no more “duck & cover.”
Women’s equality. I remember back in the '50s, my mother told me that in the Soviet Union, women could be doctors or engineers or truck drivers. That just seemed strange to me. And when you watched the news on TV, you watched middle-aged men, period. If there were any women, they were “weather girls,” who knew nothing more than how to point at a map. I recently watched a panel of economists on CNN; they were all 30-something women.
Organized religion. Back in the late '60s, a lot of us thought that within a few years, organized religion would be a thing of the past.
Dress codes in schools. When I was in (public) high school, the boys couldn’t have hair over their collar or ears. No jeans, no t-shirts, no shorts, no tennis shoes. And naked swimming classes. For the girls, it was knee-length skirts, and no pants, shorts, t-shirts or patent-leather shoes. One of our school’s principles would stop girls in the hallway and tell them to get down on their knees. If a girl’s skirt touched the floor, she got sent home.
When we were kids, we were allowed to play outside all day, with no restrictions. Nobody had ever heard of a kid being abducted. We were just told not to talk to strangers, and that was it.
