I think, in your second paragraph, you kind of contradicted yourself. If "weaponized victimization and othering" are the problem, well, victimization doesn't weaponize itself. Somebody is doing those things. So now we're at "a group of people are causing these problems".
That means that, yes, we kind of do arrive at an us-vs-them mentality - even you do, if you think a step or two further.
Now, you could be pleading for the Christian "love the sinner, hate the sin" idea - people are doing these things, but we need to not "other" the people. And that may be a real point - if "othering" is what they are doing, and we think it's wrong, then we need to be careful not to "other" them. At the same time, while we try to figure out how to help them not destroy society, we still need to keep them from destroying society.
