This all started a very long time ago but escalated dramatically under Bill Clinton. Suddenly oral sex was not sex. Lying about sex was normal. Cheating on your wife was just a small personal indiscretion. I left organized religion because preachers across the country were saying it was no big deal. Everyone said it was inexcusable but he didn't do it. Then when he admitted it everyone excused it.
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.
