Is it rude to expect guests to bring gifts to your wedding?

My first poll went a little awry because I combined weddings with baby showers and there was a lot of cultural difference over what a ‘shower’ entailed.

So on this poll I’m just asking about weddings 🎩👰

Further questions for discussion:

Is it rude to expect guests to bring gifts to weddings?

Is including where you’re registered asking for gifts? Or is it more of a subtle nudge in the direction of presents?

Is it rude to be annoyed at a guest who doesn’t bring a gift?

Is it rude of a guest NOT to bring a gift to a wedding? Why?
