Regarding the question in question, this one wasn't me but looking at them the comments here are definitely over the "Be Nice" line. (Crash Override was also being a bit of a lunkhead to be honest - their comments REEK of "I'm too special to have to read the topicality section of the help center" entitlement, but we still have to "Be Nice" when we tell someone they're being a lunkhead.)
I went and zotted the whole question as it was off-topic and cleaning up the comments wouldn't help that (plus it was collecting delete votes anyway). The rest is a matter for the grues and badgers...
The edit to TomTom's comment on this questionthis question was (part of that comment was wrong but not wrong).
With respect to the above comment, declining the flag there was solely an administrative convenience: Comment flag handling options are "Delete" or "Decline" (there's no "Valid but I'm not going to do anything" button like there is for regular flags).
If we delete a comment it's annoying to get it back (or we have to write a new one), so if I'm editing a comment to "fix" it I generally decline the flag and make the edit.
I'll be the first to admit that this is a crappy workflow but it's a time-saver and I'm a lazy bastard :-)
