I strongly support rigorous debate as a method of judging an articles quality. Simply because one does not understand why an article is a quality article does not mean that it is not. Conversely, that one believes an article to be a quality article does not make it one. The only reasonable way to resolve such differences in ideas is through rigorous debate in which all viewpoints are aired and have an equal say in the outcome.
There is no reason to disregard any argument. Regardless of who makes an argument it is valid until it is refuted. This refutation may be easy (if the argument is absurd), and may be done for any number of reasons, or it may be extremely complex and paradoxical.

I suppose these are somewhat relevant.
