No. You don't get it: what that norm states is that you can not walk as a free citizen in any business open to public, but you must be identified as a gay person in a place specific for "your kind", so nobody is allowed to enter a gay club unless willingly to identify themselves as gay, and you are forced to become a member of that place, as if you were forced to become a member of any store to be able or business in general to be able to have a drink or buy something or, merely, to wander around FREELY and
privately, which also means that all the closeted gay Italians will avoid hanging out in a club because of that norm. The norm turns a private, free citizen into a private, secluded version of yourself.
That's what the riff raff is about...
And notice I didn't talk of that norm as something in the present
