The arguing, at least to me anyway, seemed to take on a life of people with proof and those without, but who would vehemently argue it was blue (to the point of making **** up) because for them it was nostalgic.
Now, I got the nostalgia argument... "My toy was blue in 1981, and I want a blue one now!"
That to me, actually makes sense. That's valid... That's preferences and opinions being bantied about between collectors. To me no different than a guy who wants figures carded, and Hasbro to go the extra mile to make sure figure cards are minty mint, as opposed to the loose collector that sees the package as merely a short-term obstacle to happiness.
The "argument" seemed to be a lot of Scott posting a bunch of images of the figure in a brown coat, definitively, and a bunch of guys showing nothing as definitive and making stuff up even (I still can't believe a guy kept arguing it was only brown for a costume fitting... dont' ask him how he knows, he can't show you images, but he's sure he knew this).
Arguing about WHY you want it one color or the other seemed to really go by the wayside to some degree... Guys would say they'd want blue because the vintage was blue, but nobody seemed to pay attention to them saying that. *shrugs*
I was wrapped up in a separate argument about the figure itself simply sucking. Which it did.
