I agree with this. I detest cancel culture, but downvoting isn't cancel culture. Cancel culture is about fostering a climate of fear that chills speech (specifically fear of harassment a la a concerted effort to petition one's employer to have one terminated). Downvoting is an expression of disagreement at worst, and it's perfectly consistent with free expression ideals.

EDIT: This is cancel culture: https://twitter.com/wokal_distance/status/128148065056698777...
