While people may disagree with someones choices, I don't see that as bashing. Well, maybe for Bose...
People may recommend one product over another for either personal or technical reasons but that's not bashing. The fact that many may agree that other choices are preferable over one brand is not bashing, it's a consensus of opinions.
On the whole, I'd say this forum and most of it's inhabitants are pretty even handed in most matters when it comes top stating preferences.
Getting back to the more recent thrust of this thread, where it's been put forth that this site "bashes" Polk speakers, do you buy into that?? If so, please site some examples.
