Their position is that PETA is blatently using Autistic people as a tool to forward their political agenda, and doing so on the flimsiest of evidence.
They are now begging Ben and Jerry's to put human breast milk in their ice cream claiming cow milk causes autism.

The hypothesis that a high consumption of A1 beta-casein increases the risk of DM-1, IHD, SIDS, schizophrenia and autism is very intriguing and interesting for basic as well as application studies. However, some pieces of evidence in relation to human illnesses are not strong enough and should be verified. Therefore it is necessary to continue research into the role of BCM-7 (originating from both raw and processed milk, e.g. cheese) for human health.
