It is a rather sexual protest, I wonder if the event organiser did it as an excuse to see loads of tits. I imagine in his head they look a lot better than they inevitably will look in reality.
At last week's protest there was some fat guy with a sign about "deleting us from your browsing history", a clear reference to trans porn. As if people would want to look at some fat guy in that way.
They really are delusional and can't understand that they look ridiculous.
