Cancel culture, regardless of what you said, is. Basically boycotting or protesting a person or organization so the protested/boycotted is adversely effected (like harming their business or losing their job) and/or practically eliminated from public view (muting them from being seen and/or heard - closing down their social media accounts for instance or not booking them to appear for interviews etc)
This is not a one way street. It’s done by the left and the right.
