I can't get behind this campaign, because a large part of it appears to be advocating censorship of humour.
The face value difference between genuine hate pages and humour is often subtle. But their intentions are completely different. A joke, no matter how crude is not attempting to propagate the idea that rape is acceptable.
Because it's intentions are not to encourage the spread of hatred, it appears the reason they should be removed is because people are offended by them. If you find them offensive, don't view them. And I think it's pretty easy not to view those images unless you go looking for them.
Here's the campaigns 'examples' page: http://www.womenactionmedia.org/facebookaction/examples/
There is a clear overlap between the jokes, and what I would consider hateful. The majority appear to be bad jokes, and the supporters of the campaign often (understandably) find it difficult to differentiate between the two.
I can't support censorship of humour, no matter how offended I am by it. The campaign in my view has failed because it has not clearly defined it's boundaries, it's going to war with genuine hate pages and bad jokes at the same time and is causing a lot of confusion in the process.
