Sorry, it was similar enough that you triggered my automatic "tolerance is not a paradox" response. I'm sure you weren't trying to justify all forms of "complaining" with pseudo-intellectual BS so, please forgive me for lashing out :)
I agree, there's a funny thing about it, but to me it's more optimistic ;) It's like a very good point is being made, it's not perfect but, somehow, that point could be used to sharpen itself.
