Well I haven't read any of Dawkins' stuff, I'm a poor book/article reader, so I am just going by what I hear here, but it certainly lowers my interest level in reading Dawkins' stuff in the future when I hear he cannot be objective.
It is important to have differing beliefs, and yet be able to respect each other's beliefs. The only exception is when someone knowingly lies or commits an act of violence. If Dawkins can't at least respect sincere, considerate believers, then I'll be inclined to steer away from Dawkins.
