I think, and I am not alone in this, that many of them are not merely cantankrous old idiots who enjoy discord, but actually players on the other team. A surprising number have very old sign up dates and often when checking, no comments for years, then they pop up. Hijacked screen names maybe.
Many use Delphi techniques to create acrimony and get people on their side. “In crowd” mentality like high school girls is then part of it. Definitely many are either RINO or Demshevik agents. They enjoy what they do.
That is why we need a Free Republic voluntary ideological litmus test matrix.
I dunno what Delphi techniques are.
