If every HN was full of thank you posts, it would be unreadable. Upvotes exist. I prefer comments to add to the discussion, so I don’t find the users request for more information to be that baffling. Their comment was at least trying to further their understanding, which is more than sillysaurx did.

Then vote and/or report? They aren't trying to further their understanding, that much is clear when their dialogue started by saying anyone who holds a different ideological position is a grifter. They're trying to start a fight with a bystander who supported the "other".
