1) He called US Republicans 'assholes'
2) He signed a 911 investigation petition.
3) He supported Mumia Abu-Jamal.

Most people here could easily support one or two of those sentiments.

That was enough to get him sacked by a smear campaign from Glen Beck. You've maybe heard of him thanks to satirical US TV shows. Beck is the weirdest of the weird of Fox News, a living pastiche of the worst of america, the embodiment of the idiocy of Fox News. He is the 'TV evangalist' who is fucking the kids in his congregation while crying with sincerity. He is Rupert Murdochs revenge on humanity.

So who was Van Jones and why did Beck hate him?

It is all US establishment stuff, but as long as the world is subservient to the USA then you know this idiotic personality crap in the US is going to hurt us all. It's maybe better to take an interest.

Here is a good video of Jones talking to Carl Pope, the founder of the environmental Sierra Club:
