I wouldn't call it "censorship", but sure, let's say it is.

There's a reason why "this is the exception that proves the rule" is a common saying. Picking out one exceptional example of something, and using that to argue against a general point, is at best lazy, and at worst actively dishonest. I'm fine with those kinds of comments being "censored". They -- and the comments calling people out for doing this -- are boring and don't further discussion.
