Fist, you say downvoting is suppression of speech. I don't think you can really support that assertion. Then, you leap from downvoting being suppression to suppression being censorship. I don't think you can really support that, either.

The dictionary definition of censorship is suppression. I'm sorry that you dont like that fact, you can go do a quick search and check out the top 10 results for "define censorship" and you will see it says suppression.

Upvoting a comment or post gets it more views, it promotes it.

Downvoting it gets it less views, to downvote something is to censor it(suppression).

I agree with downvoting(censoring)spam plagiarism and content calling for direct violence.

Please do not continue to reply that censorship and suppression are different, if you say that back to me again after I showed you proof, then I know I'm dealing with someone who is trying to gas light me.
