Irenicus: The "idort" term is one of the rarely used terms in /a/, anyway.
Surprisingly, though, being an idort holds a somewhat positive connotation in /a/, because it would regard you as a "bro who doesn't believe in *shit (moeshit, etc.)".
I also agree with erneiz_hyde's statement. What we see are numbers and posts in 2ch and 4chan. We don't know which of these guys (aside from particular people with tripcodes) watch X and Y, the latter of which is hated by fans of X.
