In which the_dunk_tank@hexbear.net mod bans me as a "liberal"

This one requires a bit of background.:

Hexbears keep opening the_dunk_tank posts about our mods and our instance in violation of their own comm rules. That compels me to go in them and try to correct the bad faith disinformation being peddled about us.

In one such thread one commenter made a reply to me ending it with "disengage", which was a clear indication they didn't want to engage in discussion any more, which I respected.

Note that there's no indication of how disengagement works in any sidebars. And even their own Code of Conduct, merely states:

So it appeared to me this is how it works.

Later in the thread, someone kept making bad faith replies and at some point I thought, "I'll just use this handy disengage rule to avoid being further provoked". So I did, at which point I was gleefully and summarily banned by the mod with the following comment, to which I couldn't respond anymore of course.

Now I knew already that plenty of hexbears had a grudge against me for rejecting "left unity", so they were just looking for an excuse to get rid of me, they finally found enough of a plausible gotcha and all they could think of for the reason was "liberal". Note that the first person "abusing the disengage rule" was never banned or affected in any way.

Ultimately this led me to being banned from hexbear itself, but that's a post for another day.

So what do you think? Am I "liberal "enough to deserve a ban for "abusing" an unwritten disengage rule. Power trippin' mod or nah?
