Here are my more or less randomly collected thoughts on issues in this forum (in case anybody cares, which they may not):
1) I agree with Thucy about krellin's often vile rhetoric, and agree that he should be called on it most of the time.
2) I would be appalled to see krellin banned.
3) The "putin the rapist" stuff, while undoubtedly as controversially put as possible, has always seemed to be obviously a substantive criticism of a rhetorical move that putin does, indeed make very frequently, and putin has, indeed, failed to respond to it. So I except this from point (1) above. (In particular, so far as I have seen, krellin always puts what his reasoning is for this accusation, and it's always manifestly clear that he is not actually claiming that there is evidence that any reasonable person would interpret as suggesting putin is a racist; rather he is suggesting that putin uses evidence and guilt-by-association arguments that no reasonable person would accept).
4) I would also disagree with abge's claim that 90% of krellin's posts are unsubstantive. I think he most often starts by making substantive posts, and even has interesting arguments that merit response, but cloaks them in filthy rhetoric, and then often degenerates to just the filthy rhetoric if somebody responds to the latter and not the former. Once again, there is no reason, in any case, that this should be tolerated by other members of the forum. (Which is not to call for any official action).
5) I think that an "anti-harrassment" rule is completely unenforceable, and will necessarily lead to subjectivity and continual enormous controversy. Far better, I think, to just stick to the rule where personal threats are disallowed, and keep hands-off on the rest. I see no reason this thread should have been flagged, for example, and this rule, if pursued, could easily ruin the forum.
