Sorry to be obtuse. The other poster looked at your list and stated they were afraid to ask what might be next:
Easy divorce in the 70s
Androgyny in the 80s
Homosexual tv characters/Don’t ask don’t tell in the 90s
Forced celebration of sodomy in the 00s
Child rape in the 10s
And I said, referring to the post about the Camel’s nose under the tent, that the next thing would be “The Camel”.
