Should I tell my wife (please read first)

Me and my wife have been together for 6 years and we’re expecting our 1st baby that is a boy! My FIL is a little homophobic. He tries to be accepting, but says some homophobic comments every now and then especially when drunk. My wife grew up where her family wasn’t very accepting of her and got better with time. My family was very accepting right off the bat so I never got any rude comments. When I hear them I get extremely defensive and uncomfortable. So yes, we’re a same sex couple. So we moved to Texas 3 years ago where my wife’s mom and sister live with some other family. My wife’s dad finally visited shortly after we got here because her sister was pregnant and is a boy as well (she’s gay as well). Before we moved here the sister was here for 5 years already and he only visited ONCE! When he was drunk only I was near him and he went on a homophobic rant in which one thing that was said was “I come down here quite often now (about every 4 months) because I don’t want my grandson to be gay he needs a man in his life.” Since I found out we’re having a boy I’ve been really bothered when he comes up in conversation and asks about the baby. I don’t want him involved in my sons life if it’s just because he doesn’t want him to be gay. My question for this poll is should I tell my wife what he said or just leave it? As I said before she’s unfazed by comments like that cause she’s heard them all while growing up.
