Other than being guilty of generalizations, I don't see anything here that's untrue at all.
The problem is that far too many Americans today do not understand the distinction between all, many, most.
All statements here are objectively factual, with possible exception that “many,” unlike “most” and “all” is an undefined term. Does it mean 10% or 40%?
Which might tie into whether the last statement is factually true. However, even it says, “Many of the rock musicians they followed belonged to Eastern religious cults OR practiced Satan worship.” More the first than the second, I suspect.
BTW, I have long believed that the quickest way to separate the right from the left is opinion towards “the 60s.” Everybody knows what is meant by this term. Were the 60s a net good or a net evil for America and the world? IMO a very definite net evil, but many liberals still pine for what they perceive as those longlost days of peace and love.
