I mostly disagree. Saying "this should be like that" isn't a problem. When you are saying "this should be like that because it is proven by x" you have to actually prove your theory for it to be valid. Anecdotes and emotions can be valid in opinion, opinion can be valid in reasoning and reasoning can be valid when presenting facts. What you can't do is to mix together emotion or opinions with facts, at least not without bridging the gap. And that problem is in my opinion much larger in right wing discourse.

Edit: On second though it is very unlikely we will have a productive discussion here. People never seem to have been able to handle this type of discussion on HN and judging by the response this isn't the exception.

So since the quality of both the article and the comments are low I would instead recommend people to flag the story.
