I don't see that at all. I think everyone tacitly and explicitly acknowledges that the US was founded, primarily by Christians, on primarily Judeo-Christian values, while enshrining freedom of religion in the Constitution.
It's when you get a large number of people in public office explicitly fighting to bring their religion into the public space, to force prayer on schools, to question and be suspicious of anyone with different religions, that we get a problem.
The pushback you're seeing is the pushback against a majority trying to impose its faith on all Americans.
It's a huge stretch for you to take propaganda posters from the 50s and 60s, during the Red Scare against atheist communists, and project that upon the entire country's 200+ year history, and to assert that the POSITIVE IMPACT of that religion cannot be denied.
