What the heck? He did reply to the argument. He didn't call anyone in the community names, and the beliefs and position held by the author absolutely DO matter in this context.
Dang you need to really revaluate your decisions on when to post or call people out for "rule violations".
I don't see any reference to beliefs or positions in the GP comment, nor replies to arguments. "Luxury columnist" is obviously being used as a dismissive label in this thread. If you toss in "Yale" as more or less a bad word, then the entire comment reduces to name-calling. This was not a borderline moderation call.
(Btw the guideline against calling names isn't limited to people in the community.)
The fact that it's considered a epithet is more revealing than anything else.
Him being an elite - someone who knows he's intrinsically superior to everyone else by virtue of selection - is 100% relevant to his opinions being flawed.
