Yup, pointed this out earlier and a few JSO sympathisers couldn't really explain why importing more oil from overseas is preferable to drilling for it in our own EEZ in the North Sea?
There seems to be some knee-jerk element of the supporters/sympathisers of this group just out of general vibes re: the environment and being seen to cry out and protest for something even if it doesn't really make much sense.
People don't seem to have a sense of scale with this stuff either, especially with all the hype/doomerism, it seems counterproductive. For example, there have been claims/predictions for decades and it's probably a really bad idea to keep making specific one, Greta deleted tweets recently for example:
Greta Thunberg has deleted a tweet warning climate change could "wipe out humanity" unless there is a halt on fossil fuel usage by 2023.

Unless there's a halt by 2023... well the message some may take there is that we're done for anyway now so why bother. In reality, those sorts of claims are dubious and often just hype, it's still worth doing something to reduce emissions, but it's not worth getting hysterical re: dubious campaigns where you're blocking roads to demand loft insulation and now blocking roads to, essentially, express a preference for imported oil over domestic.
