I read the sermon transcript. Reverend King made the point that we live in a God-ordered, moral universe and urged the congregation to put God before material objects, which is a sermon that I've heard (with slight variations) many times in evangelical Christian churches. Hardly subversive.
I'm well aware of Rev. King's history and don't dismiss any of his communist affiliations or personal failings. However, Rev. King was definitely a force for the legal end of institutionalized segregation in America. Sarah Palin's respectful nod to King's place in U.S. history, amplified due to his assassination at age 39, is not an approval of his murky associations and certainly does not deserve the kind of opposition some have aimed at it. Apparently PDS knows no bounds.
Did it every occur to you that you can disagree with someone with being “deranged”.
