I was called terrible. You are quoting wrong!

Furthermore, because of having a different opinion I was downvoted. Hence, I deceided to self-censor myself.

I'm fairly sure the comment you censored contained the words "You are terrible" in response to "what a terrible comment". They called your comment terrible and you called them terrible.

You aren't being downvoted because of the opinion but because of the way you chose to express it.
