Ok, final post, as I find this quite silly.
There was a conversation in which only one or two posters made the point that OP's comment about LH itself contained harsh wording that perhaps could itself be considered LH about the posters. (I don't necessarily agree, but that's irrelevant)
Then OP made a humorous quip making fun of the above sentiment. Now, I'm somewhat of a sarcasm connoisseur, it used to be in my signature. The joke simply doesn't exist without making fun of a sentiment that had only been expressed by one or two posters.
Do I think anyone was "emotionally anguished" by it? Not by any stretch. But it was jarring to see the very poster who was making a whole to-do about LH, employing sarcasm to make a point, as that is by definition something that is cutting and hurtful, even if it doesn't technically meet the standards of LH.
