The fight against cancel culture is a fight against people doing things. It's literally that. "Cancelling" is just a framing device for a myriad of behaviors and reasoning behind those behaviors. If this post gets downvotes, "cancel culture". If OP's post gets a bunch of negative comments, "cancel culture".
TL;dr- There's never been an egalitarian, logic-only meritocracy, in human history, and people getting upset that there isn't one is as reasonable a choice as other people deciding to "cancel" someone.
