I disagree that it is dangerous. Of course not every opinion is worthwhile, but since opinions got labeled as too dangerous, they got much more appeal for others. Otherwise it would just be another stupid opinion.

I think this had a large negative effect on many subs since people somehow lost the ability to just ignore something or write their own opinion as a response. Everyone was screaming for mommy moderator.

Today people get a heart attack if someone writes that the earth is flat.
