The main thing wrong with Christianity is the idea its followers have that everyone must join their religion and think like them, whether they want to or not. If not for this one thing, which drives its followers to annoy people on the streets, shun anyone who doesn't practice their religion, and to force their religion into government where laws are passed based upon that religious belief, I would have absolutely no problem with it. It would be to me just another wacko religion like Scientology.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
