The founders of great spiritual movements, Buddha, Christ, Muhammad, all warned against revenge and called for forgiveness (even though Quran calls more to the due process and justice while gospels call to radical forgiveness). This is easy to understand rationally: a society with a lot of revenge keeps killing itself and keeps nurturing cruelty. Such societies tend to not survive for long.
I'm very sorry for all the Black, queer, Jewish, Arabian, East Asian, etc people who were victims of bitter oppression. I adore those of them who struggle for justice, cessation of oppression, peace, and reconciliation with the rest of the society. But I would not join those of them who strive for a war and a revenge.
Fighting against a powerful enemy, it's important to be watchful and not become the enemy's mirror image. I hope the people among them who possess more wisdom and compassion will eventually help most of them choose a better path.
