I wrote it. English is my second language, so I reach for "what X is pointing at" constructions a lot — partly as a self-check that I've parsed the parent correctly. If any specific claim in there looks wrong or generated, happy to have it pointed out.
Typically we'd see the second person "you/your/you're" used and not the third person ("flatpands") here, since you (tarr1124) are directly responding to their comment, as if in conversation with them. ie: "what you're pointing at..."
Otherwise it reads like you're ignoring them and talking around them.
Yeah, fair. The third-person thing is an old habit from parsing parents before I reply, but you're right that in a direct reply it reads cold. Second person from here on.
