I know how you feel. I had to break contact with several family members during the 2016 elections when I learned how they really felt. There are a lot of people who I thought I knew that I can’t ever speak to again after the things I have heard them say. There’s more to it than simply their political views, but, yikes, that’s as the last straw.
I’m sorry to hear it, but that’s poison in your life. Lancing a boil is painful, but it’s the only way to start healing.
