I also agree with Terry and Georg.

I don't think anyone should be banned from the tracker or from the MLs unless their actions are intentionally destructive (e.g. flooders/spammers).

This is not the case for anatoly, so in my opinion we should not take this kind of action against him.

While I mostly lurk on python-dev/ideas, I interacted with him several times on the bug and meta trackers, rejecting/closing a number of suggestions/issues and accepting a few others.  I did so merely on the value of the suggestion itself, and I can really easily ignore the tone of the message (e.g. frustrated, angry).

That said, ISTM that the main problem is that the way he communicates is not really effective and that results in an "energy drain" for other people.

This can be addressed on both the sides.
The community should ignore the tone of the messages or even the messages themselves and most importantly avoid replies that convey the same negative feelings.  People should be able to recognize when a discussion is not constructive anymore and leave it, rather than wasting time just to prove a point or to repeat themselves.  (Note that this apply to everyone, and not to anatoly in particular).

Regarding the effectiveness of the communications there's certainty room for improvement, but apparently the previous attempts to address the problem were unsuccessful.  I'm willing to make an attempt myself, as I think I have a quite clear idea of the problem.
