There is always danger. The challenge is to find a balance between values/principles and praxis. Denouncing the hypocrisy of the many "new allies" is right now counterproductive, in my opinion.
I empathize, but rather than pointing fingers, let's celebrate that the Cause has become so powerful that even these motherfuckers are joining the wave. Now it is time to add, not to divide.
How Western media would cover Minneapolis if it happened in another country

I am not denouncing Whites, I am not denouncing only police brutality. I am denouncing White privilege. The recent incident in Minneapolis and the countless examples of outrageous abuse (even you recognize the disproportionate number of Blacks shot by the police) are just the tip of the iceberg.
Your defensiveness is not speaking highly of you.
