You raise, multiple, good points. You got me thinking, and there is plausibly a legal case here, BFS is giving medical advice   ffa  through prescriptive behavior, and espousing itself a medical authority. I'm not a lawyer, and I'm sure no lawyer would take the case, but there may be a medical board/committee we could report this troglodyte to, and at least get them doxxed so we can laugh at their thunder thighs.
