By the standards of this site and (I'm pretty sure) the vast majority of its readers, dropping a phrase like that is obviously flamebait. If you want evidence for that, you needn't look further than the first reply to your post.
Since you bring it up, I'm guessing you felt that the "calling out your peers" aspect was a mitigating factor. The thing is, your comment didn't say anything about that, and readers have no way of knowing. Intent doesn't communicate itself, so the burden is on the commenter to disambiguate.
Yeah, I’m not defending that other thread. You made the correct call.
I can appreciate the irony of discussing a guy who is being recalcitrant on the subject of how words or examples make others feel and then doing the same thing. Have a good Sunday.
