Fauci is director of an NIH Institute. Directors are bureaucrats and politicians masquerading as researchers because they know nobody respects bureaucrats. There are a few exceptions, not many.
Actual science researchers can tell by listening to Fauci that he is trying to fake it through his presentations, relying on big science words he does not fully understand to stump and impress the public. Trump made a mistake to rely on him but how is Trump supposed to know who is a scientific gem and who is a fraud. Hard to distinguish; who can Trump believe?
So, fren, when you say "we don't believe your LIES" you are dead on the mark. Seconded and confirmed by an insider.
