smoking is not an appropriate analogy at least insofar it is primarily damaging to the individual (claims of second hand smoke aside), whereas exposing oneself during covid is more broadly damaging as the purpose of social distancing was specifically to avoid spreading the disease, not to oneself, but to more vulnerable individuals. moreover it can be indicative that he is self-interested, that is, by acting hypocritically, while not in and of itself evidence, is consistent with 'charlatan behavior' as is, i would add, interviewing a known charlatan dr aman. aman detractors will think he is 'being shown' but the reality is that aman or similar wins legitimacy, which the interviewer knows, since his aim is entertainment, not medicine, in his capacity as an interviewer.

it is not ad-hominem to try to understand a person's motivations for expressing a particular opinion, which is why the above poster referred to 'character' which is not specific to the definition of ad-hominem, but is in the spirit thereof, that is, distracting from the argument. but if the person has shown themselves to be working contradictorily to public health policy, especially in consideration of the hippocratic oath, you may ask reasonably what they are about.
