So yes, you can express a sufficiently contrarian opinion that would lead to banning. "All women should be treated as sex slaves", for example, is such an opinion.
But I don't think even you would argue that the reason for banning that opinion is its contrariness.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
