Why do you, if you do, feel threatened by nudity, and the existence of naturist groups?

In minnesota we don't have a lot of nudism. Most months it is too cold to go outside without a coat on. From May to August you have mosquitos, deer flys, horse flies, and black flies all wanting to take a bite out of you. Then there's the poison ivy and thistles. Ticks are out from may through october but i guess if you were nude they'd have fewer places to hide. Most beaches in minnesota are not sandy, they're muddy. It was that mud that the indians used to coat themselves to protect themselves from the insects and sunburn. Saunas and the fresh snow outside them are the most likely spot to find a nude Finlander.
