I mean, an "elaboration" would really just be saying what Lord Dave said with more words. I think he was more succinct than rude or angry.
Well, like I said in the same post you seem to be referring to, "maybe that's just the limitation of impersonal written communication". You took it one way, I took it another. Cest la vie. Maybe you've had more interactions with lorddave and have a more positive baseline assumption about his tone in a void of context. From my perspective, I don't know him from Adam's off ox, and have learned that if a random stranger on the internet seems like an asshole, it's a fair bet they are. (And no harm if/when others assume the same about me.)
Either way, he took the time to elaborate/clarify, so...the chakras are back in alignment in this neck of flatland.
