For example, "I'm such a X", or "I feel like such a X", where "X" is often "idiot", "moron", or some other words I don't like to see or say.
Such comments do not seem to fit directly into any of the "When shouldn't I comment?" categories, but I have no memory of running into any such comments and seeing anything I considered valuable information or anything fitting into the "When should I comment" categories. So my intuition says that such comments are worth flagging (at least when they can be seen without having to expand hidden/collapsed comment sections).
If I see such a comment on a comment thread without having to expand hidden/collapsed comments, should I flag it? And if so, what flag reason should I use? Should I flag it as being unfriendly/unkind? It does seem like that would fit, except that the comment is unfriendly/unkind to the commenter's own self, which is a little different than what I'm guessing the original intent was for that flag reason (flagging unfriendly comments directed at other people). And would "unfriendly/unkind" make sense for "I feel like such a X" as opposed to "I'm such a X"? or would it make more sense to use "no longer needed" for "I feel like such a X"?
