His first comment capitalized "NOT", which was kind of rude. He also chided me in a paternalistic manner "keep the facts straight please".

Rudeness isn't the same thing as disingenuousness. I was probably rude. But I wasn't disingenuous.

it's kind of odd that he would go around following all my comments and pointing out their flaws.

I don't expect you to believe me now, since you didn't believe me before, but since I was honest before, perhaps you'll hopefully have updated the level of my trustworthiness upwards: I didn't "follow you around". I was looking at the recent comments of the HPMoR thread, not your comments. I don't remember noticing who made that comment until after I had responded to it.

And I didn't downvote that comment of yours either. So far I've only downvoted two of your comments, and both of which contained false accusations against me specifically.

The fact that I corrected you again is just indicative that you're the one who's been recently making sloppy arguments and false claims all over the place. (no, Quirrel didn't echo her exact thought, no Dumbledore didn't speak of Tom Riddle in front of Harry, no Lucius Malfoy doesn't need to know of Voldemort's love of puns to take note of the word "riddle" when directly mentioned to him by Harry Potter)
