They have been fed social and progressive programming for a bunch of years now.
The Emergent/Purpose Driven Church. Rick Warren/Joel Olstein/contemplative spirituality/co-exist movement, and it is social programming and it is very effective.
At my last church, there were three speaking engagements- in the two months leading up to the election, with social justice leaders. It is HUGE industry and wildly popular. It is all over TV and books stores and radio. And the white suburban people were mesmerized and intoxicated with the message of the plight of the poor urban black man.
The church has been taken over as well.
That is what socialists do.
Try to find a 'hellfire' pastor preaching at a Bible-believing church in New England. Just try. Lukewarm as they come.
