Lazs, again you are confusing terms.
You're looking for the term atheism, which means having no beliefs, or more directly having a lack of a deity in one's religious beliefs. High Buddhism can be considered an atheistic religion.
Secularism is not a religion, and does not actually comment on any religious beliefs. It is a political philosophy of acceptance. Communists are not secularists. Thats even worse than your liberal-socialist conflation.
How so was MLK more dangerous to your way of life than Falwell, unless that danger is to your own intolerance?
MLK argued for civil rights not so much as a minister but as a public figure. Sure he used Christian principles to back that up, but he had better reasons than just to claim the bible said so. He never argued to take the rights of any individuals, and if he did I'd love to see a quote.
I never said ministers can't do good in this world, and that even MLK isn't a debatable figure in some ways, but to compare him on the level of tulips like Falwell insults those who actually use their Christian teachings for good, love and justice.
WWJD to Falwells show? I bet he'd turn the channel.
