The other comment was condescending and name-calling - this one was just pointing that out.
What is the condescending insult you're referring to by the way? Lefties?
'Lefties' used to dismiss another's point of view as invalid withiut actually explaining why is just baselessly tribal and antagonistic.
But yeah, definitely so re your second point, it is needlessly antagonising, and destroys measured political discussion (as it always has and always will)
