"Who hurt you?"
These days, that's shorthand for "I'm an emotionally stunted liberal who is so incapable of self-reflection that anyone who disagrees with a point I have must be acting from a place of unresolved trauma". It's always felt like people-who-definitely-used-to-post-to-4chan burning extra words to get to the r-slur they so desperately want to use; but with the exact kind of plausible deniability that gets their squishy bits either hard or wet.
