I was referring more to the transgender and sexual identity part, but yes I get your point it has been growing for a long time. It is incrementalism...progressivism.
“transgender and sexual identity part”
I spent my 3rd and 4th grades in Sacramento in 1973 & 1974. There was already the homosexual support and abusive sexual talks then. We had one kid whose mom dressed him as a girl and the school protected that mentally ill behavior and child abuse. My 3rd grade teacher was a total hippy dippy. She encouraged boys to kiss boys because, “Who knows? You might like it.” I was born in Kali, Santa Barbara. By 1974 it was already a lost cause.
P.S. Another 3rd grade teacher in 1974 in Kali liked to give kids a ruler/pencil box as a present on their birthdays and French kiss them, telling them that is how the French kiss. Sexual exploitation of children was already happening by the time this country left the 1960’s.
