Even if someone's lifestyle is emitting 1/10th the carbon of yours, they should still reduce it to 0 before criticizing you? Sounds like you're just trying to avoid feeling guilty and absolve yourself of any blame.
Certainly not. Being a hypocrite doesn't prevent ability to criticize. But it does weaken the argument depending on the level of hypocrisy.
I'm not avoiding feeling guilty and I know I'm not innocent. I'm trying to listen with an open mind and exchange opinions in a polite manner. (like everyone else here I hope)
