His 'free speech' (as he claims) is not the problem.

The problem is that he worked for the NHS as a senior consultant while spreading misinformation and disinformation that could seriously harm many in the general public (and probably did harm them).

In response to the 4 users below, more info (quote and paraphrase):

The Hippocratic Oath is violated when doctors publicly talk against the vaccines.

The Hippocratic Oath contains a commitment that the doctors will “respect the hard-won scientific gains of those physicians in whose steps I walk, and gladly share such knowledge as is mine with those who are to follow.” The vaccine a hard-won scientific gain of science.

The Oath also commits the doctor to “apply, for the benefit of the sick, all measures that are required, avoiding those twin traps of overtreatment and therapeutic nihilism.”

The Oath also prescribes that the doctor need “not be ashamed to say ‘I know not,’ nor will I fail to call in my colleagues when the skills of another are needed for a patient’s recovery.”

In the Oath, doctors also commit to “prevent disease whenever I can, for prevention is preferable to cure.” Vaccines have been a major strategy for prevention of disease.

With freedom comes the responsibility, and the professional title is not a right but a privilege. That makes the doctor’s statements and positions, even views, different from that of a layman. In the midst of fake news and rampant misinformation in traditional and social media, the information-consuming public need responsible messengers and valid content, especially from doctors they trust.

You CANNOT be a medical professional without a professional approach to the science of the vaccine.

If there is one sector that society is seeing as a solid group, it is the medical professionals. Why? Because they have held in their hands the reliable, tested, scientific approaches to end the COVID pandemic where possible. Anything less than that is disappointing and discouraging. The Hippocratic Oath has that unity in context when it makes doctors swear to “not violate this oath.” It also assures doctors: “may I enjoy life and art, respected while I live and remembered with affection thereafter. May I always act so as to preserve the finest traditions of my calling and may I long experience the joy of healing those who seek my help.”

Mohammad I Adil has been dangerous, the potential cause of substantial suffering and potentially, deaths.
