There are aspects of "Make America Healthy Again" that are actually good ideas but the problem is that they are tied to extremely bad ones. Like getting rid of artificial dyes in food and improving food purity are good ideas on the surface, but they're tied to dumb ass ideas like seed oil panic and anti vax. Furthermore, none of this stuff is actually being supported by law. It's all just rhetoric and the actual law and policy changes are just more pro corporate nonsense and all action taken by corporations so far has been voluntary statements saying they'll do something in the future. I think this is the real problem of the conservative movement at least in its current form. Even when they stumble upon a good idea, the fact that there is no underlying logical framework to that idea other than just further enriching those in charge means that said idea can't be implemented properly and without other nonsense.
