There were always elements below the surface, I remember hearing about the "fat acceptance movement" in the 2000s, in 1985 a Black Panther group in Chicago were overjoyed by the news that Ghaddafi was offering to send them weapons so they could become a full on terrorist group, in 1969 blacks protested the Apollo mission as a waste of money better spent on welfare, the greatest scientific achievement in mankind's history would have been better spent on money for niggers to buy Kools with?
The rot that is killing us today set in in the 1960s, that's when, as I've said before, the fundamental attitude shifted from "what is true" to "what we WANT to be true" which is the root of Clown World thinking, reality is whatever you want it to be.
But mainstream media and culture acted as filter that kept all the really crazy shit in check, once the internet leveled the playing field the crazy shit was able to swarm, multiply and network together to where it colonized "mainstream" media and culture and now we live in Clown World where down is up and up is down.
