I basically made a similar comment a moment ago I just deleted because it was flagged immediately by someone who didn't like the premise. And I was actually being fair to the author of the article I used as an example.
I wouldn't recommend deleting comments if you really believe it was flagged in bad faith. If that's the case, other people are likely to vouch and upvote you.
Fair enough I suppose. That said, I personally would rather delete a comment that potentially has a brigade incoming towards it while I still can, than wait too long and suffer the consequences of malicious people.
I mean, I still have the original comment saved on a wordpad if I decide to put it up again; but at a slightly later time when those people have moved on to whatever it is that annoys them next.
I'm also new here, so I am doing my best to curtail the effects of the malicious against me as best as possible.
