It would have been fine literally everywhere I've worked.
I'm not saying there aren't places where this can be an issue. Partly this seems to depend on the region – in the US, in particular, it seems to be a big no-no, which I find odd considering how fucking often fuck is in fucking American media – the fuck is up with that? But outside of that? It seems to be mostly a non-issue.
I didn't say we were uniquely diverse, I just said we were religously diverse. Big difference. If you're going to shit on someone, at least shit based on accurate information, otherwise you make yourself look like a pretentious asshole.

Having lived and worked in the US my entire life at various companies all over the country, religion is a huge factor in whether people take offense to it. It's not the only factor, but it is a significant one, I would guess the most significant one. Unless you have data showing otherwise, I would think you'd give my opinion at least some weight, but maybe thinking they have superior knowledge about US culture is one of those deeply mistaken views that Europeans have about themselves.

So if it's not religion, then what is it?
Let's not pretend there's anything polite about user-hostile UIs.
