In Grenoble, they have declared total freedom of bathing suits. You can swim in Muslim burkinis, swimsuits with legs, or even topless (topless women). Will this lead to diversity and tolerance? I doubt it. The most aggressive will impose their customs on everyone. Which will almost certainly be Muslims. So long will they harass and assault “sluts” (meaning women in European swimsuits) until they stop going there.
It will actually be a normal development. And it applies to all areas of life. The state clears out an area in the hope that it will become a freedom zone. But very quickly another player will step in, start enforcing its own rules, and the result is a much less free world than it was under state control. And then it turns out that the new player had it well in hand and was purposely promoting propaganda about freedom and an oppressive state. It happens over and over again. We are unteachable.
