The big difference today is that 40+ years ago, organizing a group based on fringe beliefs had a cost. People had to put real effort into finding and organizing these groups by sending out flyers and spending time in the real world. Today, it costs almost nothing to promote any organization based whatever you want -- hate, conspiracy beliefs, virtually anything that society as a whole agrees is harmful is but a few clicks away with mere pennies being paid for getting views. I strongly believe that hyper-targeting of these kinds of online ads and social media based content promotion is not good for humanity because it removes the social checks and balances that traditional less specific advertising or promotion of content have. Having people outside of the target audience see ads that promote hatred makes it more likely for them to be flagged or even cause a police report to be filed. It's a pity that big tech has completely removed human over-site of these issues in the name of "scale". Maybe "scale" isn't what humanity needs.
