From around 14:00 Choice quotes:
'The climate change movement has been dominated for thirty years by the repression and the control and the smothering of the professional classes [...] The people that have joined XR that want to turn it into a talk shop, that want to create all these rules - Extinction Rebellion is a rebellion! [...] What the professional classes like, what the educated people like is words. Words, words, words, words, words. Social media and words. Demands, more words. Social justice, racial justice, it's all ####ing words! [...] If you want to be into justice I suggest you go into rebellion. And what does rebellion look like? It's nothing to do with words.'
And that's why the liberals in XR want him out.
