Hmmm. If I don't agree with you I'm in denial? What is it you've decided I'm denying? As I see it I'm only denying that diesel engine emissions are the only or most important pollution problem that we face and that it can be resolved by banning them. And you're right, the arguments you present aren't convincing.
