I've done this for the past year or so on CHE, and even more steadily than before (although I did try to ignore provocative posts through 2-3 iterations before commenting, I'd usually fold and say something just to offer an alternative view; finally decided I didn't need the added aggravation, or the extra post numbers).
So, yeah, in Forgiveness and Reconciliation training, it's even a thing: you teach people how to listen past the provocative issues and pay attention to the understory. That often means ignoring the chaff and waiting for the actual grains to appear.
And if they never appear, then you just go on.
I got so I didn't even need an "ignore" button. I'd see a post and just click past it.
