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
