This is a ridiculous response considering a) the US 100% bends towards the religious more than the UK does, and b) the font used in the poster absolutely made it look like the word fuck instead of fvck, which the US won't allow on anything but paid for TV channels at the best of times.

I am not the least bit personally bothered by the content of the ad or the language in general, but the idea that there might be some kind of restriction on the word fuck being writ large on posters in public places is "nutty" seems a bit rich.
