A young(ish) woman who identified herself as a nudist took questions from the field on reddit, and this one stuck in my mind:
Is there still a political difference between nudist and naturist?
From my perspective, the two terms are used interchangeably. Some people might say that a naturist is more into being out in nature or the wilderness. But the two are really the same thing. Politically, nudists/naturists run the gamut.
And then there’s “naturalist,” which is not the same thing at all, but looks enough like “naturist” to cause the occasional gasp.
