Proper Tidy
Arsed
I don't think they will go away on their own or just run out of steam. Firstly, as has been said, this stuff has been around in one form or another for a long time. The advent and exploitation of the internet has concentrated power into relatively fewer and more powerful sources. I'm thinking Icke and Alex Jones here. So that imo is where you focus the attack. What these guys need is exposure (being talked about) to sustain their popularity. But at the same time you need to tackle it. Not just by laughing at those who have been sucked in (or 'woken up' as they like to say) but by attacking the sources and discrediting them.
There needs to be a militancy against it amongst the left. They call it an 'info-war'; well there needs to be a fight back. They are remarkably flimsy in some ways. Jones is desperate for attention/prone to melt-downs, Icke is already a laughing stock generally. I think the stakes are too high to just point and laugh occasionally though. Discredit and undermine the leaders. So a big thank you to those who have already been patiently doing that. Keep it up, it's vital!
Honestly the best thing the 'left' could do to stop the spread and arrest the popularity of conspiracism and right wing populism is to fill the vacuum they find space in. A vacuum which mostly exists cos the left vacated it tbh
