He's not, everything he gets involved in is already in the public attention. The recent rent issue and protest had NOTHING to do with Brand. Brand saw a popular cause and decided to jump in front of it, if anything he took coverage away from the issue and all the news was about his interview rather than about the issue.
He's like many other people, Bono, Geldof, whoever else, a cause exists, it gets attention, they jump to the front of the cause pretending to be a champion of it, take away attention from said cause onto themselves. They get loads of attention, book/album/ticket sales go through the roof, the cause is pretty much ignored and become about those individuals, these people are worse than politicians. They are the worst type of people having absolutely no morals or care. It's easy to read a paper see what the latest cause of the people is then turn up and take the attention while being seen as the champion of the people when in actual fact doing nothing at all for the cause.
Brand doesn't have views, he's a populist, nothing more or less, we never hear what he is for BEFORE an issue becomes the popularly held view of the people. He always jumps on a cause as it gets big and gets lots of media attention. Media attention whores like him just follow the attention then jump in between the cause and the camera for his own personal gain.
He has a large vocab and nothing else, he has no ideas, when he talks on the subject matter he comes up empty, when asked how to fix something or how something could be made better he rambles on like a retarded idiot or simply lashes out at the person asking the question. The entire problem with politics is people like him, people with no idea who want the power, the attention but hasn't got a clue how to make things better. Politicians who have no long term plan how to make things better just jump in front of whatever is popular at the time with no coherent plan of how to improve things but act to appease the public masses even if said action makes things much worse in the long term. Brand is like that, jump on a cause, no ideas, follows the media attention, gets upset when called out on having no clue what he's talking about.
