You're probably right, to some degree at least, but in that case you'd block the person for a couple of days, then escalate to a week, then a month, and then indefinitely. Maybe threaten a topic ban somewhere in there too, just because you can. In other words, you'd treat them like you should treat anybody else on Wikipedia who was doing the whole "tendentious editing" thing and ignoring warnings to stop (without that person necessarily operating one or more new accounts to evade a previous block, or what-have-you).

Stop icon You may be blocked from editing without further warning the next time you make personal attacks on other people, as you did at Wikipedia:Administrators' noticeboard/Incidents. Comment on content, not on fellow editors. Special:Diff/991223849 This has gone on long enough. You have been warned often enough. The next time I see a personal attack from you, I will block you for a week. —valereee (talk) 14:41, 29 November 2020 (UTC)

As for the other editor <IHA>, who is accused by some of being a bit of a hothead and jumping to conclusions and expressing them in an all-too personal way, this admin has noticed that as well, but right now, and after the final comments, there is no consensus for a block or ban. Editors who consider their behavior beyond the pale should probably take it to AE. On to the next dispute. Drmies (talk) 01:31, 9 December 2020 (UTC)
That last brought on the MJL mentorship. While I'm no a fan of MJL's work at Scots Wikipedia, I've no doubt that they're more than well intentioned; and would have made a fair and honest attempt at mentoring. If that failed, it's not on them.
If MJL (as mentor), GW, JzG, et al decided to drop their support, then perhaps there's a message for us external viewers.
The above is not an exhaustive look. There are more warnings. And far too much of the editor at noticeboards about other editors. If one reports someone else, then they should expect to be sanctioned when they show the same problematic behaviour. If one spends their time shoving people under the AN/I;AE bus, then they shouldn't be surprised to be hoist by the same petard.
That, and the fact that too many people out there seem to think that getting pissed off at right-wingers during the past 4-5 years is somehow unusual.
Getting pissed off at right-wingers is entirely usual, and more than fine. But there are forums to express that ire.
Carrying on about it like an absolute roaster in forums designed for writing encyclopaedia is not fine (cf. Just zis Guy).
As regards editors of any persuasion (political, personal or elsewise): if more edits to WP/T: than :, then probably WP:NOTHERE; if more reports to AN/I/3RR than new articles, then probably WP:NOTHERE.

is more than a bit like the MjoPants... but without the "charm"... or the shit essays.
Is Guerillero's decision correct? Possibly not.
Is the "bum's rush" narrative accurate? Certainly not.
