"Being fired for something" isn't the same as being cancelled. "Cancellation" implies a concerted campaign to pressure employers into firing employees. Being fired on the grounds that you've offended your employer or said something that is broadly unpopular are both awful, but they're different than "you've said something that offended a tiny minority of the population but they're threatening to call up our clients and slander us (and otherwise make business difficult) unless we fire you".
They did not fire you just because they disagreed, they did so because others would harass and complain until you were fired. Sorry if the attempt at making some sort of 'both sides' point went off the rails, but cancel culture was created by the right and was their exclusive domain for almost 60 years in post-war America. There was a large list of things that you were not allowed to say, to do, or even to be just because right-wing pressure groups and 'concerned citizens' would ensure that you had no job and no voice if they found out.
The only thing that is different now is that the shoe is on the other foot. I guess when some people find they no longer have license to be an asshole the transition can feel a bit uncomfortable and needing to learn about these things called 'consequences' that everyone else has been forced to endure must seem a bit strange.
