Can you point out where, specifically, this "censorship of opinions" is called for?
It has already happened. My first comment was removed, since my opinion that limiting debate to what one side deems acceptable is akin to the "Good Germans" who went along with the T-4 euthanasia program, which still - hundreds of posts into this thread - no one is willing to discuss on the rational, civil, etc. basis that the thread itself allegedly calls for.
