Oh, heck yeah. I've got the same sort of issues in my own family. In my case, I'm the sole conservative Republican in the family, so I'm pretty much radioactive at family gatherings.
Doesn't bother me, though, as I'm in Texas and the rest of my extended family are in California. I've only gotten back there to see them once in the last seven years. Oddly enough, things stayed peaceful for the most part. Maybe they missed me enough to back off on the usual gang bang political attacks. Dunno.
Tell you what, though, the country is more divided now than at any time since the Civil War. My G-G-G grandfather served with the Confederacy, while his brother served with the Union. It nearly broke their father's heart.
I see families splitting just as badly today, and the divisions seem to be deepening. I don't know what the next four years holds for us, but I wouldn't be the least bit surprised to see several states secede.
That part remains to be seen, but I fully concur with the rest of your post.
A similar thing happened to some of my ancestors, WF. In my own family it’s my two liberal children who give me heartache and grief. Good thing they live far enough away to keep the peace. They literally shun me because I am a Christian conservative. I haven’t seen that son for 11 years. He does not communicate with me at all. The girl usually comes once a year around Christmas for a couple of days. It is difficult for me to keep my tongue during that time. It is so uncomfortable, I’m relieved when she goes back home.
