You're generalizing on a large scale. No good ever comes of that. There are plenty of sane Nintendo fans and over-the-top Sony fans.
Though I will admit that a lot of Nintendo "news" sites get linked here that are just propaganda vehicles that pander to those who believe what they want to believe. I don't think they can be considered representative of the greater user base, however.
Of course, this entire thread could be the work of EA and the Illuminati ... hmm.
