I think the homebrewers react so aggressively because the protocols are having limited success and any critique collapses the whole “we will recover/its only a matter of will” construct, as it is obviously built on quick sand. When you question the effectiveness and success rate of homebrew while suggesting a very long term orientated more complicated and unknown solution like scientific research, you take away hope. And since hope for a near term homebrew solution seems to be essential for many, they react viciously. At least thats my take. Its the classic shooting of the messenger phenomenon.
If the protocols would actually work, they wouldnt feel the need to react so aggressively. They would try to convince us or leave it but not be aggressive since they would be progressing along nicely and thats all that matters at the end.
I think the solution would be to let go of this claim, that homebrew has cured or will cure a substantial number of PFS victims. It hasnt happened and wont happen unless we make progress via the foundation. If that solution is to tough of a pill to swallow we could agree to disagree for the time being; let the homebrewers do their thing and we can discuss other issues together in a civilized manner. But the attitude, that homebrew is the solution for all is destructive, since it implies that anyone not recovered is responsible for his condition. In that regard I believe many in the homebrew community will have to make at least a partial concession, just like we are making one by reinviting them to propeciahelp.com.
I have no problem with homebrewing (even though I am not believer), as long as the universality claim, i.e. the claim that it will fix everyone who isnt lazy, is let go off.
