Accusing someone of “virtue signaling” is itself virtue signaling, just for a different in-group to use as a thought terminating cliche. It has been for decades. “Performative bullshit” is a great way to put it, just not in the way you intended.

If the OP had a substantive point to make they would have made it instead of using vague ad hominem that’s so 2008 it could be the opening track on a Best of Glenn Beck album (that’s roughly when I remember “virtue signaling” becoming a cliche).
