Since you love your boyfriend who was raised by the "sexist and racist" father, one assumes he turned out OK. So why the threats about not seeing the grandchildren who don't even exist yet, neither does an engagement one assumes since you call him your boyfriend?  Seems very premature to bring up a world of pain and make threats against a family like that.  These are people who could help you and support your union and love your potential future children. Archie Bunker had his charms. And honestly, there is a tendency out there today to shut down opinion not deemed politically correct enough, that I find far scarier than many of the opinions the SJWs  are too delicate to allow in their presence. Ironically, you would probably tolerate extreme views on women and sexuality from the religious group mentioned. Most opinions are the product of socioeconomic, political and religious norms located in a time and place. They only seem wrong when those parameters change. Family transcends this.
