"Muddy the discussion"? You mean like having two opposing viewpoints represented? Having an actual discussion instead of choir practice? Well, that's the problem isn't it? Far too many people are here for choir practice instead of discussion, and a lot of that "music" is pretty crappy given the varous claims about geeks and "superior" intellects. Too few people post correct information about this and related topics.
And your crack about "same worn-out arguments" cuts both ways. Or at least you would realize it if you have any genuine insight. The right answer doesn't change just because you're tired of reading it.
