I recently caught my chud family member watching some dumb youtube video about “experts lying about COVID” (yes, chuds are still malding), and like, what’s the fucking point anymore?
You can be as gracious, understanding and in good faith as possible, but people will believe whatever nonsense some idiot influencer says is the truth. It makes me so mad, and unable to argue with these people, because their irrationality makes me irrational. Fuck.
Anyway, how are y’all doing? 
I have a cousin who is similar and I force dominance by saying “you are wrong and this is dumb” until they change the subject. Somewhat effective? I don’t need to communicate past that at least lol
