When interacting with humans, too much openness and honesty can be a bad thing. If you insult someone's politics, religion or personal pride, they can become upset, even violent.
Especially if you do it by not even arguing with them, but by Socratic style questioning of their point of view - until it becomes obvious that their point of view is incoherent.
You haven’t proven that your point of view is any more coherent, just attacked theirs while refusing to engage about your own — which is the behavior they’re responding to with aggression.
Most times, my (the questioners!) point of view never even enters the discussion. It certainly doesn’t need to be for this reaction.
Try learning how someone who professes to be a follower of Christ but who also supports the current administration, what they think Christ’s teachings were for instance.
I'm very honestly wondering if they become violent, because using socratic method has closed the other road.
I mean if you've just proven that my words and logic are actually unsound and incoherent how can I use that very logic with you? If you add to this that most people want to win an argument (when facing opposite point of view) then what's left to win but violence ?
