Attempting to analyze fanboy mentality only begets fanboy arguments. Just look where this thread has gone in only two pages. You're generalizing amorphous collections of people - undefined groups that will inevitably be viewed differently depending on who you ask. Stuff like this serves little purpose besides starting arguments, and honestly, this stuff really pisses me off.*
Seriously, why do we have to talk about how ______ group is being hypocritical? Or how ______ group is suddenly "crazier" than another? It's silly. Why can't we just talk about the games instead of having all this bickering between people that happen to prefer one console over another?
To use the example in the OP, so what if people claim their aunt/uncle/whatever thinks Kinect will be totally awesome. If you perceive them to be biased based on their post history or whatever, take their comment with a grain of salt and move on. You don't have to go all "omg fanboy!" on them, neither directly nor via threads like this. Pigeonholing people like that can be quite offensive and it often leads to arguments, especially when you jump to conclusions about someone who DOES NOT have the post history to back it up (like that dude that jumped on CGI a few months back for supposedly being anti-Sony lol). Of course, fanboys are often blind to the fact that they're fanboys, so it's not unusual for them to get offended even when the accusation is right on the money.
My general policy for posting is to debate with those that can be reasoned with and ignore those that can't. Claiming someone's biased does nobody any good, and it certainly never leads to productive discussion. Chances are if they are truly biased, anybody with half a brain will see it and ignore them anyway. Either that or they'll get all offended and go "omg fanboy!" which, like I said, is not a wise thing to do.
So yeah, talking about fanboys on an open forum isn't a very good idea, as can be seen in this very thread. As such, I am locking it.
*Really pissed off actually means I'm just really annoyed, as that's about as angry as I can get. :P
