It's annoying when comments from one side are censored. Debate is healthy. A reasoned person should be able to listen to both sides. Should be able to tolerate opinions they disagree with.
There was a poster on the Brexit board on MN a couple of weeks ago who was trying to get someone banned because they did not agree with their views.
Trying to silence their opponent. MN refused to ban and quite rightly so. The poster then threatened a flounce because they did not want to hear this person's views (which were not rude or disrespectful - just they were a Brexiteer and the complainer was a Remainer).
