I agree with you. As a boomer who was exactly 4 yo when NOW was formed I had zero to do with the femnist movement or legalizing abortion. IMHO it is the silent generation who did this those born during WWII which was the generation before the boomers.They would’ve been in their late 20’s and thirties in 1973.
The silent generation ranged in age from 15 to 35 in 1960, so they were the dominate 1960s generation as far as youth and youth leaders go in music and drug dealers and such, their parents were the government and the institutions etc, and boomers like Sarah Palin had not even been born yet.
