No, old hippies are a subset of Democratic party people who were the demonstrating leftist rabble rousers of the 1960s. Most of them settled down to become school teachers and other government employees. Some went into media. Their children, not hippies, became the balance of the Democratic party. So did some of our children, those who swallowed the hubris of leftist teachers.
I know this to be true. My younger brother was a flower-child in the 1960s; and, he recently retired from education. He can't talk to me without lapsing into vulgarity and profanity and pulling the race card. His children are just like him.
They hate their conservative counterparts with a passion.
You don’t know it to be true, because your simple and incorrect view of the 60s is shallow.
By the way, what years was your brother getting his degrees?
