Okay, there's a difference between being a freak and being a normal and INTERESTING person... Normal doesn't mean your BORING, neither is being a freak make you interesting at all...Life is pain~
Normal furries are visually uninteresting at furry gatherings. Who would you talk to, as a journalist, to investigate the fandom: the dude with the Iron Maiden shirt that otherwise looks reasonably well adjusted or ACID HORSE?
The crazy looking ones are believed to have more invested in the fandom and are better representatives as a sort. Which makes sense in some ways: you wouldn't talk to the waterboy of a football team for the team's thoughts on the game.
The football comparison was just blah. Out there..... Of course you wouldn't interview the waterboy, because he's a scrub. You would interview the team captains, because they're normal and interesting. No one wants a freak to lead their team.
There's a difference between interviewing a fat-ass and a perfectly-normal looking human being. Ya know what I mean? You make a valid point there though =P
