Social media. It's unregulated, and allowing people to fall into echo chambers of hate. When all you see is unchallenged radical nonsense you become a radical. The social media companies don't care what people see, just that they stay on the apps as long as possible. Young men are a particularly vulnerable group - when you feel disenfranchised and worried for the future you're the perfect target for easy answers from hate groups. And if you get fed more and more of that crap because you watched a bit, it soon becomes all you see unchallenged.

We urgently need social media regulation across Europe - not bans for children (pointless) but complete reform of social media to benefit all ages. Control of the algorithms need to be taken out of the hands of the big US & Chinese tech companies who use to to create addiction and maximise "engagement" to maximise profit, and instead it needs to be run for the benefit of the citizens / user. Public Service Social Media is what we need - much like Public Service Television ensured balanced and healthy TV across Europe in the 20th and early 21st century, we need the same for social media.

Social media is the common factor between the rise in far right hate groups across the UK, US, France, Germany, Italy and more. The changes in the Netherlands are a symptom of the disease, not the disease itself.
