"On the other hand, any comic book "professional" who engages in this level petty-minded bitch-assery automatically loses all whining rights whenever mere fans behave similarly rudely toward creators."
Shouldn't it be more that they lose all such rights when John Byrne is being rude to them, Byrne being the target of this comic?
Of course, it's not as if Byrne's ever needed an excuse to be rude to someone. Or perhaps it's more accurate to say he's all too willing, ready, and eager to make excuses for being rude to others...
