There is nothing you can/could do. The endless war against intelligence and focus on just believing what some screaming asshole says on talk radio, combined with the dawn of the internet being weaponized to spread that brain rot, and here you go. Maybe if you can go back in time and murder Ronald Reagan before capitalism gets so out of hand that they can buy the government ¯\_(ツ)_/¯

I think the point is not "this is all TikTok's fault", the point is things like TikTok makes it a lot easier to spread misinformation. People have shorter attention spans nowadays, and they prefer to spend their time consuming short form content such as the kind found on TikTok. The problem with this is that it takes a lot more effort to correct wrong information and educate people than it takes to spread misinformation. For example, it's much easier to clip something a politician says out of context and to make a 5 or 10 second clip for people to watch, than to convince people to watch a 5 minute interview or read an article for context.

And even though I don't use TikTok, I still kind of insert my self in here; I don't have the mental fortitude or patience to read every single article I come across, so I often read diagonally, check the summary, or (more rarely) just stick with the title.

Well, this being the BBC their take is NEVER (ever, ever) going to be that the empoverishment due to a social, political and economic structure than massively benefits the Owner class whilst empoverishing the rest and uses propaganda to distract the masses and to make sure any redistributive ideologies are un- or at least under-reported, is the one to blame for those most hit amongst the "plebes" are going to rebel and latch one to the only "non"-mainstream ideologies that do get reported about - the Far Right.

This is because in their own country and, to some level internationally, the BBC's function is to be a cog in exactly that propaganda machine.

The last thing you'll ever going to see is the news media who portrays "two sides coverage" (I.e. all subjects getting reduced to a dispute between the two main parties) as "fair" "journalism" covering any subject as a problem of how mainstream politics benefits the well-entrenced Owner class, especially the news media from a country were the Owner class is mainly made up of the same families as a century ago. At best, they'll cover the near-mainstream "blame outsiders" movements (such as the Far Right), never those pointing out how much of the blame rest on well off local elites

Not surprising, given the same people are pushing the same rhetoric all over the world.

near total lack of moderation

Disagree. Social media is built to favor creating and then selling huge name influencers to your users, and because you cannot become a large influencer/streamer/w/e without essentially being uncritical about the world, or being critical in a way that swings completely to 1 side of the aisle. This is in itself a form of moderation that only ever allows some critical voices to succeed, but only if their critique furthers the divide among the working class.

Because they’re Nazis.

But why do people become Nazis?

People are not born Nazis.

Understanding why people become Nazis helps prevent people from becoming Nazis, even if you think there's no hope for the fucks who've already dived into the ideology.
