But Buddha Never Disparaging is one of those buddhas that walked on this earth and didn't say anything rotten about anyone. He is the quintessential Buddha most people consider buddhist. He is the eastern answer to "turn the other cheek". If he's it, I'm not a buddhist.
I know my grandmother, the quiet one, was really a buddhist and was able to practise the axiom, If you can't say anything nice, don't say anything at all. Someone, stop me before I speak again.
