They're allowed, but it is courteous of them to refrain.

And yet, not _required_ to if they don't want to.

I agree, I only wanted to point out that they can I they want to. I didn't say they have to

Edit: I'm being downvoted so I want to explain - the internet is a huge mishmash of different cultures and all I wanted to say is that it is allowed to swear because I though that maybe, in their local one, it is not and they think it's universal

Let it go, downvotes don't matter.

But I’d rather not say it, online or in person.
