I agree with you on demographics, but disagree on your explanation. (Although I'm curious what mechanism you posit between Islamic migrants and less nudism...)

I agree with you on demographics, but disagree on your explanation. (Although I'm curious what mechanism you posit between Islamic migrants and less nudism...) I think the demographics explanation that really works is that nudism as a philosophy belongs to an older generation. I was raised by nudists, and spent many an awkward holiday in various nudist clubs or camps as a child, and the customer base was already dominated by older people back then. A lot of the for-profit nudist colonies have closed down or shifted to semi-nude, because there's so much less demand. But don't worry, the dedicated nudists still get nude, they form clubs and rent out private camps.
