The first and easiest way to know that your doctor is completely brainwashed is when they say, "Vaccines don't cause autism."
That statement is a matter of cult-like faith in the system of "scientism" and anyone uttering such a statement is publicly demonstrating their absolute obedience to the vaccine cult.
It's like Third Reich supporters shouting "Heil Hitler!" Or left-wing nut jobs claiming there's a "climate emergency." These are dog whistles of obedience to tyrannical regimes rooted in lies and psyops.
