Honestly I still discuss online but it’s very rare. Mostly with teenagers since they are usually more open.
There is a problem of even where to confront with reason. Most of the time you hinder more than you help on mainstream social media, because more comments on a post will boost it on the algorithm and distribute the original poster’s message further while they remain wilfully ignorant.
pro tip
I’m not in the US
even if I was it’s my right to find political debate in the internet something not worth getting into
