An interesting take but one that I'm going to push back at a little. "Don't be a victim' isn't a violent phrase because there is no violence attached. We must be careful of the words we use and the overextension of definitions. It may be an emotionally abusive phrase, but that doesn't make it violent.
Secondly, there's a difference between someone being a victim and someone holding a victim mentality. It's perfectly possible for someone to believe they are being horrendously oppressed and experience no real oppression whatsoever. Why? Because human beings are self-involved. You will come across these people in your career in social work. There are people for whom 'victim' is a status and a way of life and you can read more in the way of transactional analysis to find out why.
With regards to the groups you have mentioned - and more importantly the careful blendng you've done of Marxist theory (oppresor and oppressed) and a sort of post-structuralism (I can identify my own truth) - you will always find people to be the victims. Everyone is the victim, this is the message being forged by the back and forth in identity politics. When two people have a valid claim to 'victimhood' they will attempt to outflank each other with their immutable (or mutable characteristics).
It's not that I think you're wrong. I think genuinely distressed people must receive help. I think that help should be individual and therapeutic in nature rather than the societal route of encouraging people to be professional victims on behalf of their group, we should be encouraging them to see how they can overcome the constraints of their life on an individual basis. There is nothing psychologically healthy about many of the 'activists' that have taken control of the narrative - they will lead their followers into a blind alley of poor mental health where they become mired in their own anger and see the world only in terms of intersecting aspects of group control in which they are constantly being victimised.
As you said.... everything is a social construct, and that includes all the group identities you've mentioned. Whether or not you think that construct is helpful or not depends on your position. Where I'm standing it most definitely isn't.
