I heard about this on the show - I can't believe it's become such a big issue!

Surely, whether minarchist or anarchist, political or non-political l(L)ibertarian, the basic rule is always the Wiccan-like principle of 'An it harm none, do what ye will.'
If you're not in favour of the 'protest' then don't go. You can even openly say it's a bad idea in your opinion - I can see no problem with any of that.
But, as a true lover of freedom, every single person on this board should proclaim the freedom-based rights of the women and men involved in the demo/ protest/ whatever to go ahead and do it whatever way they please.
Personally, I'd love to turn up to the event wearing a pair of plastic breasts!
