Credibility isnt dictated by a single quantifier. You could just prove yourself knowledgeable, but you’ve done nothing but make laughably incorrect claims. You haven’t even been confident enough in your lies to actually claim you’re knowledgeable about any specific subject.

have fun impersonating a physician. it’s a crime in every jurisdiction i’ve checked and i have screenshots

First of all, you don’t have any way to even know if I am a physician or not. You obviously do not know enough about the medical field to make any reasonable assumptions. Secondly, even if I were “impersonating a physician” it’s only illegal when you are giving medical advice or trying to prescribe medication in certain states, or when you are attempting to practice medicine without a license.

So I guess we can rule out law as one of your supposed fields of study.
