I don't really see how the example you've given of being downvoted can be equated to cancel culture.
You had and clearly still have the ability to express your views on this website so in what sense are you "cancelled"?
If people don't like what you say they're free to downvote it. It can be helpful if someone gives you some feedback on why they downvoted you, but its certainly not an obligation
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.
