Before I begin, I'd like to point out that I am also a dirty hippie. I have no problem with avoiding GMOs, only using soap on the essential areas of anatomy, pissing on a compost heap, brewing your own kimchi, all that jazz. Hell, I wash my face with honey infused with herbs I picked myself.
There are some crazy people out there.
People who want to use coconut oil as an SPF on a baby.
People who refuse antibiotics for an ongoing/worsening infection.
People who think that onions absorb toxins.
People who think contact with icky chemical products (aka conventional body care) will poison them instantly.
