I have a parent who has ramped up their use of social media extensively over the past few years, and uses it to post highly-charged political things frequently. I sometimes post political opinion too, but it is seldom, and when I do it is using civilized language and is evidence-based. My parent's posts, sometimes daily ones, are in a tone that is not backed by any evidence and sometimes have no context, is often stuff that Snopes would snuff out, and is really mean. I agree with their political slant, but the tone and babbling fervor is unbecoming and not helping to advance a good agenda. It doesn't affect me, except when the posts offend mutual friends, and I understand my friends in common separate us as individuals but it makes me so sad to see this person whom I've respected paint themselves with such an ugly, dumbed-down brush over and over again.
I don't think I can say anything and I know this is a common problem with older adults. What do you do to not get annoyed or provoked to speak up when you see your parent has told the entire state of ____ to go * themselves? It's so off-putting and antagonistic and it's ruining their own relationships, which I don't think is their goal. And no, they are not senile. I cringe that in a few years my child will be able to see this stuff.
