It's really hard to tell on the internet. I saw no indication it wasn't just a guy that wasn't sure and did no further research after being firmly told they are smooth, actually.
It's my favorite argumentative tactic. I've been in a months long debate with youtube losers about whether one of every Pokemon would beat 1,000,000,000 (one billion) lions
I am, because for all the effort people put into copying and pasting pokedex entries, I can simply reply with "but a billion lions is a lot of lions, it's too many lions" and get another dozen replies
It's just funny seeing people work themselves up over someone thinking a wrong thing about a video game. It's not like I'm harassing people or anything
