Yeah, I know what ya mean, and I've heard this advice/argument before, possibly even from your goodself InCharge. But my reason for doing battle with them is not primarily to convince them about the merits of altmed. I'm well aware that that would be an exercise in futility, though my impression is that at least a couple of them are possessed of a sufficiently open mind to entertain the theoretical possibility that it is they who have been duped, and not this 'poor young woman'.
No, I consider it primarily a matter of honour, an exercise in intellectual honesty if you will, to engage with them. In other words, I'm testing my own beliefs, assumptions, etc. in the face of my fiercest critics. If (as I fully expect) my beliefs emerge from the fracas relatively unscathed, I will consider it a vindication of sorts. There is a certain satisfaction in obtaining unintended and unwitting validation from your sworn enemies.
If, on the other hand, I consider they have whipped my a$$ in a fair fight, then I would be honour-bound to reassess my own position. Either way, I benefit, and truth is the ultimate beneficiary. I do not, and have never feared the truth, so this is my way of inviting them to prove me wrong.
