Assembling a collection of someone's past statements to make them look bad is not "simply citations", it's a courtroom or political tactic, too aggressive for good conversation—i.e. for HN discussion—and because it breaches a boundary, yes, rather creepy.

You're not supposed to go around "confronting" people here. Let them add context to their own statements if they want to. Personal details or history shouldn't be brought in as ammunition.
