All Argue No Accord

Someone whose only purpose in conversation is to argue/criticize about the nuances, technicalities and factualities of a statement rather than simply acknowledging the other person's general point and moving on. The said someone will likely come off as aloof, annoying, condescending and overly skeptical. Such sort of people are often SJWs or pedants and found predominantly on Reddit, Twitter, YouTube comments or some other online community.

Of course don't get me wrong, being the devil's advocate is vital for critical thinking and impartiality, but there are plenty of occasions when somebody's point or remark is better left off standing on its own. Sometimes a chill atmosphere has already been established and it seems rather unfitting to ruin it with an overly sober rebuttal. Sometimes you just wanna shoot the breeze without seriously getting into something, y'know?

EXAMPLE 1: This is the last time I'm posting in that community. I just wanted to share my heartfelt thoughts but the people there were all argue no accord.

EXAMPLE 2:

Me, shooting the breeze: Honestly, I think dreams reflect all of our unconscious desires that we normally wouldn't realize when we're awake, I'd recommend reading a bit on psychoanalysis, it's some interesting shit
Overly sober Individual: The subconscious isn't scientifically proven, FYI. We can only make deductions through empirical evidence such as neurological patterns within the brain.
Me: Ok dude.
