With regards to homeopathic remedies, I would argue find store that sells any health products that
doesn't have at least a small shelf dedicated to homeopathic remedies. I agree with you that the basis for the homeopathic remedies is non-sense, but it also strikes me as a caveat emptor, to a certain point.
As for the other half, are you suggesting that only those of liberal politics would ever buy organic or fresh produce, or be taken in by the marketing of Whole Foods? The statement reads as a non-sequitur, and I'm not sure how it is relevant.
Whole Foods sells an image and a promise of organic, and I'm pretty sure they will meet the current US legal definition of organic for whatever they're selling. It's not a relevant factor for me when buying, but I wouldn't call people who do buy there "gullible", as I'm pretty sure Whole Foods is giving the customer exactly what they want.
