What do you want me to say? The statement "The BBC is liberally biased" is so loaded and contextual that it's meaningless. It would have a different meaning if I said it than if you said it, and god only knows what someone reading it would interpret it to mean.
I'm generally much more comfortable dealing in specifics than vague generalities. Otherwise we just run around in circles defining our terms, establishing the frames of discussion, etc. I'm fine with it now and again, but overall I'm just tired of it.
PS-Your first link borks the column width of this thread, which is a pet peeve of mine. Could you use
TinyURL for it and edit your post?
