I'm low-contact with a couple of my core family. When we do meet, the other relatives are usually nice enough to just stop any political conversations or rants. Every once in a while, one slips through and I just ignore it, but our interactions have become infrequent enough that it's maybe yearly.
It's heartbreaking to both see some real opinions in some cases (some of which are products of their eras, and some of which have softened), but I also mourn the lack of immunity to conspiracy theories and propeganda on the other; I have seen almost a polar shift in one relative that really shocks me.
