If a majority of Americans ARE religious, and if being religious 'usually' involves thinking everyone should also be religious, then it stands to reason that those who resist religion would be considered dangerous and be mistrusted by many.

That doesn't necessarily follow. Being religious doesn't necessarily mean thinking that other people who are religious are in any way to be trusted, when they've got the wrong kind of religion. When I said that most people here would put religious fundamentalists pretty high on their list of people not to be tusted, I wasn't excluding churchgoers from the people who'd feel that way.
