Wow this is growing into a huge campaign to silence (natal) women, isn't it?
There is a lot of grim online, all we got to do is shine light on that.
Can't get a billboard? Well we can screen shot and print out the stuff folk might not be aware of, the sex side of this. We can leave them in the newspapers in cafes. We can tape them to lamp posts, back of loo doors, mail them, etc.
Yes it would be awful if kids were to see it, but kids are being sterilised because people don't know.
