Well we had one on whether 2 foreigners speaking in their own language to each other was rude or not - the OP was intimating that it was extremely rude.
Then we had the one that opinionated rape within marriage wasn't possible, and if you remember, myself and others highlighted the BNP's ignorant views on rape.
The BNP are notoriously sexist, so it would make sense to target a site such as Mumsnet would it not? After all, they say that the problem with the world today is working mothers.
