It's not a numbers issue though is it. It's not like we had riots because of the release of some numbers. It was a response to a particular event - a triple murder. The trigger has been fear. Yes, it was misdirected but countering something as visceral as fear with some numbers about migrants isn't really going to help IMHO.
We see this amped up on social media. The rape gangs in Rotherham - Elon Musk asking "Kier Starmer is this still happening" for example. Britain First seem to be all over the fear angle. It's easy to dismiss these but this stuff seems to be surfaced for people who aren't even following them. I'm sure someone will be along to say "well my Twitter feed doesn't have them", but who gives a shit. It's happening.
I still believe that leaving social media, particularly Twitter, is necessary. By sticking around on Twitter, no matter how anodyne your feed is sends the message to your contacts that it's still ok to be there. But you don't know what they're seeing, what they're being promoted. If all the good people leave it can finally collapse into a toxic hellscape. If Twitter doesn't fail then we'll see the other social media companies roll back Trust and Safety teams too and exacerbate the issue. In a way, Twitter has to fail and be seen to fail.
Of course, another idea would be to flood back and argue the toss there. However, with Musk as owner I cannot see a path to success - he'll make sure his message is amped up and other social media companies may see this as a success and take the same steps he has. Again, rolling back Trust and Safety and inviting back all the facists.
