Welcome to Less Wrong.

I don't think much people here hate Christians. At least I don't. I'll just speak for myself (even if I think my view is quite shared here) : I have a harsh view on religions themselves, believing they are mind-killing, barren and dangerous (just open an history book), but that doesn't mean I hate the people who do believe (as long as they don't hate us atheists). I've christian friends, and I don't like them less because of their religion. I'm a bit trying to "open their mind" because I believe that knowing and accepting the truth makes you stronger, but I don't push too much the issue either.

For the "that acts more like Eliezer thinks it should" part, well, the Coherent Extrapolated Volition of Eliezer is supposed to be coherent over the whole of humanity, not over himself. Eliezer is not trying to make an AI that'll turn the world into his own paradise, but that'll turn it into something better according to the common wishes of all (or almost all) of humanity. He may fail at it, but if it does, he's more likely to tile the world with smiley faces then to turn it into its own paradise ;)
