Why are Facebook allowing fascists to advertise?

What ever is happening on facebook?

An advert has just appeared on my Facebook page for the New British Union, with a link to their website.

I hadn’t previously heard of them, but it seems they are a group of fascists who are trying to resurrect Oswald Moseley’s British Union of Fascists from the 1930s. Apparently they’re led by a man called Gary Raikes. He was once the BNP’s boss in Scotland and close to party leader Nick Griffin. He has adopted Mosley’s paramilitary uniform, posting pictures of himself online in a black peaked cap, black military fatigues and leather boots.

This really disgusts me, how can Facebook accept advertising from people like this?
