It's Now OK to Frighten the Horses

I can recall a phrase that people used to use (maybe they still do, though I haven't heard it in a while), to indicate that they were reasonably tolerant:

I don't care what you do -- just don't do it in public and frighten the horses.

I presume it dated back to when there were lots of horses around, but it was still occasionally cited in the 50s-60s.

That is a long intro to a short item from Sweden, where public masturbation is now legal:

A man who openly masturbated on a Stockholm beach has been acquitted of sexual assault in court after it was ruled he was not targeting a specific person, with the prosecutor saying it's "okay" to play with yourself in public.
