As is often the case, there is no conversation here. There may as well be a sticky post saying that the guy was wrong because there's nothing beyond that. So why not raise the topic of what constitutes peaceful protest or even whether they are choosing the right targets? Britain has just committed to being carbon neutral and is actually doing comparatively well in terms of climate change policies in what is a global issue. Why aren't these people barging into the US and Chinese embassies if they want to make a statement? Striding into Mansion House isn't going to make a dick of difference if for every tonne of CO2 we're saving, the US is barfing out another 100.
