So with today's amazing ruling I am finally seeing my fiance's family's opinions on gay marriage rights. Luckily most are for equality or have no outward opinions, however my future SIL and especially her husband are very opposed to it. Her husband is apparently very homophobic and doesn't want to spend any time with gay people. They also have 2 young sons so they're extra protective.
So my question is- My best friend is gay and is going to marry me and fiance. We are having a destination wedding so it will be 3-4 days of everyone mingling together. The wedding is pretty small too. I'm worried about my SIL and her husband. I feel like I should "warn" them that my best friend is not only going to be there but is a huge part of the wedding. My fiance isn't a fan of his sister or his BIL so he says its none of their business and we shouldn't tell them anything. I agree that it's none of their business, but I'm worried about their reaction if they were to "find out" that weekend. I want to protect my best friend. homophobia is NOT okay at my wedding and I feel that people act better when they are prepared.
So what do you guys think? Let them know beforehand? Or hope for the best? Should I be the one to tell her? (we aren't THAT close) or should I tell his mom (I'm closer to his mom) and have her tell her?
