About the below, that the food industry is most likely a secret hidden funding source doesn’t make the FA/BP/FC movement incorrect.

This is a fallacy and failure of critical thinking and of discernment.

The FA/BP/FC movement should be evaluated on its merits or lack thereof (and there are indeed some merits, especially before the movement was hijacked by its most extreme elements).

While it is important and interesting to know why a largely-harmful movement achieved cultural ascendance, who funds them doesn’t make them wrong or right — corporations like the psychopaths that they are will throw money at anything that advantages them, regardless of its truth value.
