I have a problem with the flawed logic:
You can vote and still end up having a revolution. Especially, if as is claimed, the former achieves nothing. Not to vote seems rude in the extreme given the sacrifices made to gain it. Not voting is not a revolutionary act, its just sulking.
Having said that, his main thesis is correct. Huge numbers have no representation and there is no option for real/meaningful change. On that basis, more power to his fatuous elbow. Oh, and mentioning Boris Johnson in the same breath as Russell Brand is like comparing a charmless snakeoil salesman from eighteenth century Mississippi with a court jester. Too different and ones a massive cu.nt.
