this sort of thing was bound to happen at some point. groups of people seem to always focus on differences rather than similarities once the group is big enough. ancestral health was a small club trying to get noticed; now that it's a player on a much bigger scale, subgroups are going to form and bicker over who is the most right. this happens with everything: governments, religion, athletic teams, etc.
in a way, it's sort of good news, because it means ancestral diets are gaining much wider acceptance and that might lead to more availability of quality foods...but the backstabbing still hurts.
