Inappropriate comments

My dad and brother make inappropriate comments about my husband! My husband is Korean and they make comments about his eyes and say he's "secretly from the bad side of Korea" and today my dad said "I don't know how he knocked you up three times...his pecker has to be microscopic. Asian men have tiny dicks" I'm 1. Livid and 2. Grossed out that he'd even talk about my husband's dick. I honestly feel like shutting my dad and brother out of my life for good. I hate how disrespectful they are about my husband ! Am I being overly dramatic? What would you do?
