First Post - Seeking Family Advice

Although I have lurked for a long time, this is my first post. The time has come…I need some feedback/advice from the OT.

I have an older sibling (early 60’s) who lives several states away and posts some extremely inflammatory political diatribes on FB. (I don’t have a FB account but my wife and kids show me the posts - I don’t see all of them, but they show me the really outrageous ones). I almost always disagree with his positions on the merits, but that doesn’t really bother me too much since I have a lot of friends and colleagues with different views. However, he doesn’t just criticize political figures or policies… he makes really vicious and condescending personal attacks against supporters of the opposing party. And while he doesn’t single us out by name, it is clear my family and I fit squarely in the group that he routinely trashes, calls names, etc.

The other day he posts a picture of our Dad (who passed away in 2011) on the anniversary of his death. My wife shows me the picture thinking it was some type of sentimental tribute… then we read the caption which says something like “Sorry that you are gone but I am actually glad that you aren’t here to see what a joke our country has become…”. I miss my Dad so much and I am so pissed that he reduced my Dad to a stupid political prop on FB.

I have never challenged him about this or any of his other stupid posts. I'm a pretty easy going guy, but this really burns me up every time I think about it and I can't seem to let go. What should I do? Keep quiet and just fume inside? Confront him and let him know what a dick move it was? Would appreciate any thoughts or advice.
