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? 
you can, a lot of people leave religion because they start thinking about beliefs they just uncritically accepted their whole lives. what you can’t do is force someone to actually confront cognitive dissonance.
In that way I don’t thinknreason carries the day. You are finding a person who already had doubts and told them about options. Which is the story I hear most is that they had already not been emotionally fulfilled and then when a better path opened up they tried it.
