When will the courts extend the prohibition of dancing at public area DC memorials to all public areas?

II'm glad to see it is against the law to dance at the Jefferson Memorial and I was wandering if anyone knew when they would prohibit dancing at all parks,streets,playgrounds and all outside areas. Dancing is a lascivious display of sexual affection that undesirables practice and I'm so glad to see the US government has finally banned it in DC public areas.
