When a problem has nothing to do with white women, they feel the incessant urge to do something about it. The issues that they “fight for” such as BLM and Trans Rights rarely impact or trouble the white woman personally and they feel like they need to "do something about it" but that just includes screaming and yelling. White woman rage goes hand in hand with an unfettered and annoying Social Justice Warrior, typically called Karen.
"After this Karen walks into the ice cream parlor, she becomes a little upset when she sees the guy in the MAGA hat. Karen started yelling at the guy and I couldn't tell what she was saying, but I just knew that it was white woman rage."
