Age gap?

This is my boyfriend and I. He is newly 32 and I'm 24. My parents don't like him purely because of the age difference and because "he's not who we pictured you with". I've been dating him for a year and a half and haven't budged. I won't break up with him because of there closed mind but I wish they would actually try. Any tips on how to make them at least give him a chance?
