Stay true to yourself. I have been the conservative black sheep of the family for years. They treat me somewhat as they would treat the “funny uncle” or “crazy cat lady” of the family. We have a rule not to mar visits with political discussion. When my husband was alive, we would end political topics “accidentally” brought up by my liberal parents by simply stating, “Our votes canceled yours.”
As for FB, I’m on there as a pseudonym strictly to discuss music and have dropped/blocked many overtly political “friends” when I find their posts offensive.
That’s funny that they think of you that way. I am looked at as crazy as well. I am coming to the place where I look at that as a badge of honor.
