When these attacks take on a racial or gender-focused hue, I think they end up having a terribly ironic effect: further isolating the group they sought to protect (e.g., POC, women, etc). That is, they win the battle, but lose the war. Each of these stories reinforces in my mind to not associate with those that are higher on the oppression totem pole. I know it is not their fault, and I feel bad for doing so, but the risk/reward simply does not make sense. It helps that I'm a loner anyway.
