Having a vegetarian wedding would be rude. You see, this is NOT your day only. If you want to make this day all about you, then you and your fiance should have a private ceremony and a private celebration. Once you involve other people, you turn it from ME to a celebration involving others. If you invited people over to your home for dinner and you knew they hated corn, would you serve corn anyway because it's YOUR HOME and you like corn? It's the same thing for a reception. If you don't want people to enjoy themselves, then don't have a party. If meat sickened you that much, you wouldn't be marrying a meat eater.
