MTG is not a good guy; she happens to be right on this occasion, but she continues to hold repulsive views, and should not be seen as an ally. In her case, my enemy's enemy is not my friend.
About the anaesthetist: how would he identify a patient as MAGA? I think he may be being truthful when he claims to have been hacked, because surely an anaesthetist would be aware that patients waiting for an operation tend not to have "MAGA" tattooed on their foreheads even if they do support some or all of that (undefined) "organisation"'s beliefs. When would he have the opportunity to ask them?
