Anger is a fairly good indicator that you've got a strength of feeling about something - it's not a very good tool for resolving how you feel. Feelings pass like weather, the important thing is to focus on the climate - and if the climate is too angry, then everything you do will be suffused with quiet rage. Many people live like that, I don't think I'd like my lifetime to be spent that way.
And what I mean by 'winning' is that each group is trying to outflank every other group. Marginalised groups are now fighting between themselves more than they are looking at the bigger picture. That's why you have Black vs Jewish narratives springing up, why there are complicated questions about whether trans-men should be allowed at LGBTQ+ retreats because they didn't grow up male. It's why Trans-Women and TERFs are at each other's throats. They're all trying to demonstrate how they are the most oppressed, instead challenging the entire narrative that oppresses all of them.
In a capitalist system, that oppression is poverty. If you remove poverty and buy people the space to think, to integrate and to cool their anger then many of the problems society faces may resolve a little. It's not the complete answer, but it's an important part of the puzzle. Who gets to win if you can't talk to me because you think I'm an X - and I won't talk to you because you're Brazilian? It isn't you. It isn't me. It's continuation of the status quo by identity obsession.
