I tend to have a good idea of how people are going to react to an article, so they could always ask me. I would much rather MDL have a system in place so they would not have to ask me. I would say either disable comments or move the comments to a general discussion thread for articles dealing with legal issues, violence, and infidelity. Without fail, those get combative and negative, usually pretty quick. They also tend to stray from the original article.
The purpose is not to stop users from being able to express themselves, but to lighten the workload on staff, and make users feel that MDL is a place they feel comfortable expressing themselves. Users are very passionate about Asian dramas, so of course there will be disagreements, misunderstandings, and even some unwanted behaviors. That is how most things are. That is okay, and there is a system in place to deal with that.
I actually think this suggestion would be both a wise decision and fair to the user base. Wise because it saves staff time combing through reports and individual comments that can be used if not on other things, then used on reports and individual comments where it can make a difference. I would consider it fair to the user base because disabling would make it so that no one could comment, or moving comments to a general discussion thread would let all users know what they are possibly walking into. No one says it has to be permanent. And it can be adjusted as needed.
I would offer two additional thoughts. One is that this would not be necessary (or as necessary) if comments that were against the rules here were taken down quickly. People are only capable of so much, and there is only so many hours in the day. Two, which is related to number one, being that users who make comments also need to be more responsible with the freedom they have on the site. Be nice, kind, give the benefit of the doubt, know everyone has a bad day, and all that stuff.
