Maybe partly virtue signalling; I can't say. It is certainly possible.
My point is that the discomfort of seeing yourself as you are has some degree of value BECAUSE It is uncomfortable. Softening this blow also minimizes its gravity. From the standpoint of the oppressed group, the gravity of the message has more import than whether or not the receiver is comfortable with the message. I would prioritize increasing the gravity of the message--even if hyperbole or satire is needed--over comfort.
