politics

Basically yes. There is nothing really new or different from the modern right-wing extremist ideology to the old Nazi ideology. The fundamentals are the same, always. They always go after minorities (first demonizing them, then jailing, deporting or killing them), they always strive for authoritarian leadership, they always combat science and education because science/education (or rather the universally accepted truth/facts) is kind of fundamentally incompatible with right-wing extremist beliefs (which are based on fear, feeling, outdated traditionalist values, fundamentalist Christian religious values, and a big load of plain bullsh!t). And of course they're going after everything that's inclusive or social because all they know is fear, hate, division and destruction. It's basically a cult which eventually wages war on everyone who thinks differently. They will always start with the ones who can defend themselves the least well and then move on to bigger targets (e.g. first illegal immigrants, then all immigrants, then people of color, then religious minorities, then political minorities, and so on). Eventually, they will demonize everyone who doesn't think their exact way or is in the political opposition etc.., in an effort to divide people.

It's like a cult and it needs to be stopped. Don't fall for the trap that it's somehow different today. The only thing different is that they now have the internet to rapidly spread propaganda and misinformation everywhere (and all lesser educated or young parts of the population are likely to at least partially fall for this stuff), and that Western countries have stronger constitutions which will not crumble as easily as e.g. the Weimar Republic before Nazi Germany happened, because that constitution had a big loophole to exploit. But they might still find exploits or fill enough key positions with loyal fascists that they might be able to effectively sidestep the constitution, in effect installing a fascist, authoritarian government that can do what it wants, hunt who it wants, and be immune to legal repercussions. Don't underestimate them, they are very good at manipulation, lies, division and in general causing mayhem. They thrive from chaos, because from chaos they can then also create a powerful executive force to "restore law and order". Also they do not care about what you think about them or their actions. They will move quickly and mercilessly to achieve their goals, and so any opposition to them must also be quick, decisive and resolute, and not hesitate.

They also currently gather immense wealth behind them currently because super-rich people/companies like riding on that bandwagon because it will grant them even more power and influence in the short to medium term (this was also true in old Nazi Germany btw), because there are no pesky or costly regulations limiting them anymore, so they will gain short-term economic benefits from siding with the extremists, and as we all know, in capitalism, money is everything, and morals don't matter. Elon Musk in particular is particularly clever and ruthless because he essentially managed to buy parts of the government, meaning he will make the government favor his own companies and plans. It's kind of unprecedented corruption I think, but of course it's a dream for any super-rich commercial entity. No regulations, no fines, do what they want, even direct taxpayer money into their own pocket. As much as you can, stop using, buying from or otherwise supporting big companies who openly side with fascists. You can vote with your wallet. In capitalism, voting with your wallet (what you buy, where you buy from and most importantly what you don't buy and where you don't buy from) is a very effective secondary vote option. Also stop using Facebook, Whatsapp, Instagram, Threads, TikTok, and so on. In those platforms, you are the product, and when you use them less, they can generate less money from your data, behavior and interactions.

Long-term, Nazi ideology always leads to societal division, hate, crimes, bad living conditions, lots of deaths, and eventually wars. Because once they've taken control of the inner political systems, and jailed or killed enough minorities they think are "harmful", they will always look for the next minority, and then the next, and the next, and then they'll be after you. And there will be very few if any legal ways of stopping them. After that (or even before), they will turn on their neighboring countries and start wars with them. Because they always need a new common enemy to hunt, they live based on the belief that they're more superior than others and that kind of grants them the right to take what they want and oppress those they deem "inferior" (Nazi ideology in a nutshell). When they don't have any easy targets anymore, they will look at other countries to invade. Any neighboring country in particular needs to be constantly aware of that.

Slightly longer term, if the USA fall to the right-wing extremism, it will lead to its weakening and downfall (allies will also turn away), and China will become the undisputed global super power in the world.

Longer term still, climate change will cause massive mayhem planet-wide. Since fascists are anti-science and pro-economy, and economy is pro environmental exploitation, they are accelerating the problem even further. They will deny the problem exists until it hits everyone, including them, in the face. Hard.

Unfortunately I don't think there's a way to save us from climate change regardless, unless the whole economic system drastically changes, which will probably not happen until the catastrophe is there, but we can absolutely fight fascism and extremism, and in doing so this will also delay climate change slightly, granting us a few more years of "quality" time on this planet, before it all goes to universal sh!t.
