I have a good friend - she's actually going to be an in-law, as her daughter and my step-son are engaged. Our relationship is close. She has different political views from DH and I, which is fine - many of our friends hold different views and we actually have had very interesting discussions on occasions.
But this friend is prone to making posts on FB that are easily debunked by checking Snopes or Factcheck. Sometimes the posts are just things like "This common food is actually poisonous!" or "Boycott this manufacturer for such-and-such reason!" but many of them are politically-motivated misinformation. She is not originating the post, but reposting a viral anti-X post or article.
My tendency has been to reply with a brief "X website has an article about that - it's not quite accurate to say....," and the link to the article. But I noticed that I've been doing it a lot with her. Probably nine out of ten of my Snopes-ings lately have been in reply to posts by her - probably once or twice a week. I don't want to seem argumentative, but I also do not like to leave blatant misinformation laying out there unchallenged.
I do not reply when she says something that is just an opinion - I do not want to debate politics on FB. I'm fine with debunking things like "combine these two ingredients to make a great cleaner!" but obviously politics is more fraught.
Do folks have an opinion? Am I being rude in replying this way? Would it be better to just stop posting Snopes or fact-checking websites articles in response (which will drive me crazy to leave serious misinformation unchallenged)? Unfortunately, I can't just take her out of my feed since this is one of the main ways we stay connected. Would it be better to approach the subject in person sometime, and mention she might want to check Snopes etc. before reposting something, since there's so much misinformation out there?
