`  :Proving a negative is devilishly difficult. That is why the burden of proof is on the one making the claim. State a reliable source verifying the claim that there is no mention whatever of ACT in any protocol or recommendation of any of the organizations mentioned. Moreover, cite a source verifying the claim that ``mention`` of a group in a protocol or recommendation constitutes recognition or acceptance by these  organizations. Cite a source even to verify the claim that any of the groups mentioned ``recognize`` or ``accept`` advocacy groups as a matter of policy. Most especially, cite a reliable source that ``recognition`` by these groups is a requirement to be a part of the ``mainstream`` of the ``mental health professional community`` (or even what that community is). Most especially, cite a reliable source for the claim that ACT's ``advice is not sought by these groups, nor intended to be so`` by the organizations mentioned.  :Without verifiability of the statements made, the entire section must go, and I am prepared to delete it. It can be reinstated when verification is found.  : `
