The title was “Summer nudity is becoming natural in Finland”. Of course nudity is and has always been natural. It is a different thing if it is legally and socially accepted.

I don’t see signs that in Finland the acceptance of nudity outside one’s own private property had been increasing during the last years. You could still easily be prosecuted for “public offence against sexual morals” if you are nude a public place where many people see you and at least one of them doesn’t accept it.
