The big shift got a huge bolt under Clinton. TV programming started pushing homosexuality and Christian bashing big time. Think back to the television shows of the 50s and 60s and look at the utter filth that exists now. I honestly do not know if we can recover as a society.
A large part of the “Arts” community believes that part of their job is to shock or provoke. The media believe this too. This means they have to continually elevate the shock value to top previous levels. There is no end to the depravity in sight.
