That being said, I'm tired of people saying the most effective way of protesting garbage like this is not watching it. Unless you are a Nielsen family, CBS will never notice if you're not watching. If you want to protest this, call/email write CBS to tell them why you're not watching the Grammies; that's much more effective.
They have already both lied. This is yet more of the same cultural sewage. It is no longer whether or not I stay clear of it. There are social costs and as a culture we are all affected directly or indirectly.
Unless and of course you believe in social Darwinism and have enough $$ to hide behind a gated community, then we are all vested in making sure Our Culture does not become more toxic.
