I feel both perplexed & amused at those people here who simply cannot abide someone's calmly disagreeing with them AND presenting factual responses to their statements. Instead of engaging further & trying to learn something, they block after two or three reasonable exchanges.
Echo chambers are seductive, I guess.
In my opinion, it's a sign of immaturity: being unable to tarry with conflict and learn from the Other.
(Standard caveat: ofc trolls, racists, & fascists don't merit engagement.)
