As a Russian who's been thinking about what could've been done about Putin's many moves towards authoritarianism, I say this: I don't know. I dint think anyone knows either.
indsight is 20/20, so good luck trying to convince people to act now, before the far and distant future is here; it's probably part of our nature to not be that much concerned with the long-term, as it's the short- to mid-term that keeps us alive, i.e. fed, sheltered, hopefully healthy etc.
At this point, it feels like history is indeed very cyclical, at least society is, and now anyone left of outright fascism seems to be in minority, with many others either failing or refusing to recognise what's likely coming. I don't think it's new, either - I'm sure people of our ages had things to compare their situation to during the Nazis' rise to power and subsequent events, just like we look back to their times and wonder how in the world could we possibly let that happen.
It's probably best to vote and to protest and to be politically active and all that, before the right-wing or some other authoritarian group manages to manipulate its way into your government, local or higher, and start doing all it can to make you not even think of voting or protesting or being politically active. The caveat is you just don't have any guarantees that any of that is going to work.
What's even more important to remember is the fact that we cannot come up with some universal solution that's going to always work the best way possible in every political and economical and social circumstance. This is what makes recording history and experience so important - it will allow us and those that will be after us to analyse the multitudes of factors and tendencies that lead to things and hopefully figure out reliable and effective and predictable mechanisms for society to function and prosper in mutual respect, egalitarianism, support, etc.
My last take is probably a little controversial: I think we shouldn't ostracise people we see as fascist or right-wing or authoritarian, etc., but rather be welcoming and supporting, giving them respect, community and opportunity to speak and be listened to with kindness and understanding; many turn to violent and inhumane ideologies because, well, they don't value themselves, feel threatened, humiliated, afraid, or something along these lines. It doesn't have to be true, because it's about how people feel, and we must work with how people feel and influence that on emotional level so they feel like they being in a group that's based on being "anti-woke" or just "anti-" something - that's a dead end; they should feel like they belong to groups that envision future and prosperity, where people know they can be trusted and can trust, where they can respect and be respected. You may not like it, but you have to understand that the human psyche can be very flexible and eventually turn a person you could easily turn into a human-loving ally into a bloodthirsty fascist just because they couldn't find their place anywhere else, so instead they're easily picked up by a group that manipulates confused and lost people into a sense of community and belonging.
Fascism has to be the unappealing option for them, and that requires a mind healthy from trauma and loneliness, the lack of that feeling like you've been played and robbed of something you own - like some great historical period the mouthpieces promise to get you back into if you yell at teenage girls for wearing bright-colored hair and rainbow pins.
The suits did. You know, so the line goes up. Because we're all gonna die otherwise or something.
