It most certainly is PC, as politicos are the ones driving this as being the only, 'correct' way. They should focus on important issues, but that doesn't line their pocket the same way.
I stand by my rant above, and did so realizing that the PC push is strong in places like WI to remove "milk" from nut & legume products. Their reasoning is deeply ridiculous however. Any numbs kill can tell the difference by reading the label.
What irks me is trying to make things taste like something they are not, and making that your leading market strategy. If you crave something that tastes, feels & bleeds like a burger, EAT A Burger. Otherwise, have some pad Thai.
Chemically, animal & nut milks are similar & have been made for centuries (I'm guessing), so I find that less troubling.
