Even in the US, it heavily depends on where you live. If you are in one of the big west coast cities, I would imagine you can observe a situation similar to Europe.
I felt like that joke from one of the more recent seasons of Silicon Valley, where the episode revolved around one of the characters "being outed" as a christian, was very on point, from what I have personally observed both in SF and Seattle. A bit of background on the episode: one of the CEOs of partnered companies owned a gay dating site. No one had any concerns or issues with that, but as soon as some people found out that the CEO was christian, all hell broke lose and the following quote was dropped "You can put micro doses of LSD in your cereal and people will call you a pioneer. But the one thing you cannot be is a Christian."
P.S. The show is obviously pretty tongue-in-cheek, no one seriously claims you cannot be Christian in those areas or that you would face hostility due to it. But people will definitely be questioning it a bit.
