The TOS (clause 4) implies the arrogant presumption that "professionals" know better than the rest of us.
For instance, Clause 4 road-blocks any possible fruitful discussion of the suicide "problem" in the Pali textual tradition, and devolves to politically correct censorship.
The medical profession and the ensuing medical-industrial-complex it's created are recent historical advents, and relfective not of scientific knowledge but a trade bent on professionalizing itslelf to gain and maintain its dominating status through a propoganda campaign inovling the disingenuine pursuit of its own scientification.
"Professional" is merely a label, and in essence means, "I make money at it." Medical professionals are professional by this narrow defintion, but any expansion of the definition does not legitimize the OPINION MONOPOLY of the medical-industrial-complex. True legitemacy comes from those who doctors serve, not their "professional" peers.
If we were to take the TOS Clause 4 seriously, we'd have to delete any mention of the Four Noble Truths here as they are premised on a medical model and could easly be construed as medical advice.
We should also delete any comment of the form, "I take x drug for y problem" as that implies advice also.
