Earlier quoted context omitted.
A wedding is one of the most fundamentally public events that have ever existed. The purpose is so that as many people as possible should know that these people are taken. Asking guests to not take photos is such a faux pass that the couple has destroyed their reputation completely. They can have a quiet and private ceremony instead if they have stage fright.
> A wedding is one of the most fundamentally public events that have ever existed. Not sure why you think that? Although weddings can be in public places, they don't have to be and it's quite common for only invited guests (ie not the public) to be present.
I feel like it's pretty strange (and mildly rude) to insist no one take/post photos of a wedding, and also very rude to take/post photos when asked not to.
