Its not the fact that they defend Nintendo, its how they do it and the way they speak to people. Loads of people defend Nintendo on here and have no problems. Nando for example is someone I see posting that kind of stuff and how he doesnt find all that much interesting about the other consoles and you never see people jump down his throat, because he posts normally.
And before anyone jumps down my throat, yes I know it happens on both sides. We all know Sheikah will argue for far too long :p
