Nah, they don't care for my words. I know when to give up.My advice is if it really stresses you out, you shouldn't go anymore.
However, I would also say that you could also change their minds if you do keep going. If they continue to believe that hateful crap, that may spread. I don't know, you know your family better than I do but I say keep going and try to change their minds. Even just by being there maybe. It's up to you.
Loving your beard. :3Rawr Im a bear.
