They do not like ANY other religion than extremist right wing Christianity where I live. I haven't met any that have a bigger problem with nonbelievers than they do with Jews, Muslims, and in a lot of cases, even Catholics and Mormons. They get all uptight about Catholics and Mormons where I live to. We have exactly one Catholic church and one Mormon church in my whole home county. There are no non-right wing type churches here. We don't have any UCC or MCC type churches at all. Someone would have to drive 75 miles west to attend one those churches.
Anyone who is Jewish and wants to avoid an hour of misery listening to the high powered used car salesman style pitch about Christian churches they should be attending to save their soul, keeps their head down or learns to say Merry Christmas like they mean it.
It sucks here, in other words. People stop you in the aisles at the grocery store to demand you tell them which church you attend. I tell them I go to church online at a church in another state. That usually shuts them up.
That is an interesting question. I would like to know why there are some that have a problem with nonbelievers more than other religions. I know they hate atheists and agnostics where I live. At times, I have leaned toward agnostic and sometimes toward atheist and have always caught hell for it. When I tried Buddhism for a while, I just got the usual uninvited sermon from random people about going to Hell. It wasn't any different than the crap they give me for agnostic or atheist.
