The trouble with "call out bullshit" is that the commenters taking this approach usually overestimate their comments and underestimate their provocations (by a good 10x); and do the opposite for comments and provocations coming from the other side. This compounds to quite a bias—and does a lot more damage to the threads than they realize or intend.
It just leads to a downward spiral and (eventually) scorched earth, and none of that is what we're here for. We want curious conversation and interesting threads.
I see it not as "name-calling". But if this is against whatever the powers that be see as the "spirit of the site", I shall remain silent.
Back to lurking it is.
