 Sandstein apparently thinks that everything not being a compliment is ipso facto derogatory. There is also another possibility that hasn't crossed his mind: neutral. No English dictionary has (derogatory) or (offensive) label next to the definition of the word nationalist. However, in Sandstein's native language the word nationalist does have a derogatory undertone. Here is the link to the definition of Nationalismus in the most authoritative German dictionary (Duden), where it has a label (meist abwertend) which translates into English as "mostly pejoratively". In German it's used as a pejorative, in English it isn't and it belongs to the neutral register. I suspect that Sandstein mixed two entirely different usage contexts for otherwise related words with the same meaning, in two different languages.
 It was not my intention to make any kind of personal attack. If you look at my edit history you can see that my behavior has been nothing short of exemplary. I have never heard anyone complaining about being offended by calling them nationalist. More often than not, it is I who is on the receiving end of abuse which sometimes provokes abrasive responses. If someone said that they are offended I would've stopped.
 Sandstein's condescending comment about me apparently failing to understand something (what?), justifying the "educational" component of the block by such lack of understanding is borderline insulting. Perhaps Sandstain trains his dog by taking punitive measures when puppy does something wrong, but may I remind him that we're dealing with human actors here that are not Fachidioten with blinders that only respond to Pavlovian stimuli dispensed by the master with his block^Wstick. An administrator should not be making such comments when blocking other users. They shouldn't probably be thinking of editors as offenders that ought to be subject to corrective measures (blocks) for their infractions (policy violations), but at least they could keep it to themselves.
 OK, let's say I crossed the line with nationalist name-calling. I didn't mean to use derogatorily, but I can accept that it is not an appropriate conduct. But what does that have to do with ARBMAC and the excessively long block? As I far I can see the guidelines on the WP:PA require posting a message on user's talkpage and seeking mediation. None of that happened. PA is a community-approved policy which takes precedence over anything ArbCom decides, or any admin "broadly interprets". A week is something that trolls and bad-faith editors get. Surely it's too excessive?
 This whole circus is a result of content dispute with the user who submitted the enforcement request. It was not made in good faith and his ulterior goal is to remove me from editing a set of low-importance articles that are currently not in a NPOV state. He also submitted a sockpuppet investigation against me with evidence such as last-year's sarcastic comment of mine on a sister project, as well as edits that I made years ago. With all that in mind, I must say that Wikipedia community has become very effective at giving partisan editors tools to target undesirable editors - a Byzantine collection of policies which admins overzealously enforce without a second thought, and without thinking of a big picture. Admins in fact are incentivized not to involve themselves, which basically gives the enforcement gun to POV-pushers which are intimately acquainted with all the glorious details of the relevant wikilese. I urge admins to think outside the policy-enforcing request-observing mode and think whether blocking me in any way helps to resolve the pending content disputes.
