FIL has some interesting "political" views. He often makes comments when we see him or shares things on Facebook that I find extremely offensive and ignorant. He'd be the first to like/share posts from Britain First and the like, despite the fact that if you accused him of having borderline out and out racist views he'd deny it. However today he shared this post on Facebook and I think it's gone too far. I'm itching to comment on it, as I would challenge anyone else, but DP would prefer to ignore it to avoid a falling out. AIBU?
