That is a non-sequitor. But it logically continues your illogic.

[tdadams]

You think it's logical to take a layman's word at face value when they say a doctor or scientist is wrong? If I said you needed a kidney transplant and your doctor said you're fine, would you take my word for it?

Inquiring into someone's credentials - what makes them qualified to state a doctor or scientist is wrong - is not only thoroughly logical, you would be illogical and remiss to not inquire. Only a fool would take the word of the layman at face value.

But to each his own.
