Having their genitalia out is too far. Butts and tits are not genitalia. What else is going too far is burning down a fucking Park.
Let me also ask you what you think about nude bike rides, where dozens, if not hundreds, of people cycle nude through a city. Is that too much for you?
Nope, that can easily be exempt as a form of artistic expression and doesn't fit into the type of actions I'm referring to. If you've seen the images it's very clearly artistic expression no different from the body paint artists that are also in Seattle.
