It's probably not fair but I see it like a coach who gets criticised for his player's actions. @WDW1974 is seen as the "face" of the anti-NGE crowd. Since it's about impossible to keep track of every user name that shares his opinions, it's natural (though you're right, unfair) to attribute most anti-NGE thoughts out there, especially the ones that pickup steam, to "@Wdw1974 and those who agree with him."
A coach picks his team - I understand that people here are free to post what they want when they want - without being told by @WDW1974. He might call them minions, but I always took that as a joke. So your analogy does not work.
And since you are always very angry every time someone makes some generalisation when they criticise anything financial, I would think you should use the same standard when you critcise others.
