I don't want to typically involve myself in these threads but I feel like I need to address this:
If we are banning someone specifically for being toxic to specifically a staff member, and not anyone else- I will simply have to disagree with the notion. If it's just because he's being toxic in general without what it mattering the person, that makes sense.
In the hypothetical situation where it's specifically because a staff member is attacked, that suggests that some people are more important as people than another not just as members in the community but as humans in general. That may be true in terms of keeping the wiki functional, but if I got the same comment am I not allowed to say anything about because I'm "not important". We should be a community that is welcoming to others, the staff being protected by stronger punishments makes a situation where if the Staff member becomes corrupt and toxic, the normal user has no defense nor can they fight back because of power. We should all be talking to each others as equals, and treat each other as equals. When a dude gets attacked, we should all respond the same way regardless of WHO the victim is.
There's also the matter of the reason for attack. People don't say slanderous things without a reason, we're all humans- we're all suspectible to emotion. Emotions rile up for a reason, there must be some truth to the attackers words, exaggerated or not, much like how many beliefs and myths are forged by or around some sort of truth, or they won't say it at all. Saying that they're making up lies right away and their words are baseless and, in my opinion is borderline gaslighting, saying that their lying to themselves to make them attack another. No matter how angry, we shouldn't just jump the gun and just instantly ban them without question and not even consider their viewpoint because they don't have power or if they say it in a wrong way (such as an attack). As an example, many parents think they're always so much above their own children the don't even consider their opinion just because they were loud about it- they wouldn't listen to their children if they were quiet and polite either, because they think their own opinion is just so much superior, how does the child feel? They would have to speak loudly to at least have their opinion heard, but if they do that, we get a situation where they get punished not for the cause they feel like they're pursuing but the behavior of "being rude/toxic" instead.
Of course maybe I dont quite get something fundamental about society, so my suggestion can just be thrown out if needed. Afterall, out of the entire wiki I think I hate arrogance the most to the point where people live in my head all of the time every day of my life, including myself sometimes. I just feel like we need to understand that no one should have special privileges or protections and take every opinion for a matter seriously enough to at least consider even from the little guys with no staff power who want to voice themselves. It's just my viewpoint that I feel is important to share, even if it's just a mere inferior normal member's view
