Reputation can help I guess, but reputation shouldn't effect information and a persons ability to understand.
Well the Birdman article only attacks Quackwatch's reputation and doesn't say anything about Gary Null, so I figured that's why you posted it, to diminish the arguments made in the article through diminishing the reputation, which is contradictory to what you're saying now.
A person should be allowed to listen to what he wants without any enforced biases thrown at them by others.
I figure people gain more by experiencing things than listening to others. So if you are open to listening to anyone, you open up more routes to travel through and investigate yourself.
Sure, but it's important to listen to different sides and sort through them and decided which parts of which arguments are most valid. You're posting your beliefs about health, I'm just posting mine...
