Here are some ladies making an interesting and subtle point. In fact it's so interesting and subtle that simple souls like me cannot understand it.

I think it revolves around the idea that everybody's vagina is different. And that you should shout about this and wave your vagina in the faces of the general public in case, by not knowing this, they are somehow repressing you. Sadly these woman, by doing something I cannot do, have offended me and oppressed me. Whilst I have no vagina I demand the right to wave my vagina around too. And until I am granted this right I will never rest in my fight against inequality.

Also, I'm pretty sure if I got some mates together and we started displaying penis diversity in town on a Saturday afternoon, we'd all get arrested. Well who cares.... Fuck the matriarchy! Power to the Penis!
