That is what happens in some Muslim, and some Jewish weddings.
Those weddings, though, are not state subsidised, I suspect, whereas UK universities and their activities are. Not that it's acceptable in the 21st century anyway to be cleaving to such a crass, barbaric concept.
If you don't like it, you don't have to go.
But if you want to go, you have to accept it? Or can you, say, publicly campaign against it...
