The "I know what I am doing" fallacy

One of the final retorts by a defender of a suspect scheme usually invokes "it's none of your business", argument, which usually takes this form:

A: Acme XYZ is a scam because ____, ____, and ____.

B: I know Acme XYZ is not a scam. I know what I am doing. It's my business, not yours.

This is a total red herring, because it neither argues against the premise, nor argues for the counter-premise. It is completely unrelated.




This argument is frequently followed with various related fallacies, which are listed below:
