Lack of education : History tells us what happened and how. But, people find it boring. It is true that what it is in the past must stay in the past but it still teaches so you do not make the same mistake again.

Make one main enemy/villain/ the cause of the problem (even if it is not): The most effective trick ever. (think like you are at work, you hate one colleague, you find out that another colleague hate the same colleague. You become friend.)

Make a second enemy/villain/ the cause of the problem (even if it is not): So you diffuse more problems (safe side - figure of speech.)

As one says: Divide and conquer (always works).

BUT ALWAYS a minority as it works better. You need to please the majority.

In general people are tired of ineffective politics: so they try something new and/or it resonates with them, meaning they see that it is maybe true that the problem is the example (s) given by the fascists/nazis/neonazis etc. But, they will not check if it is true as they think the politicians know what they do. Even if, if you think about it. Anyone can be a politician, you need to know how to speak, to present yourself well, to have a vision, to know how to gather people together, to lead. The rest you delegate to more competent people who know their fields.

Once the hook works, you work with the emotions, some facts (fake or not). You slightly change the narrative so it is matching your "vision", "ideology". This is where, usually, you can get them as you can double-check if it is true or not. This is where you see the true journalists at work. And through asking questions.

Example: LGBTQA+ community (quite a """""trend""""" to bash at (sarcasm)). A lot of politicians say that it is destroying the society, family, we need to protect the kids (the ultimate red flag of all) etc. One just need to ask them (politicians), the right questions. In what sense it is destroying the society? Etc, etc etc. So, you can show that what they say, their ideology is just fake, anti-human. etc. But, people do not do it or few. You can apply for each point of their speech.

(Besides, the most homophobic person is a gay in the closet. Grindr never lies!!!!!!)

Then, control, media, press etc. You slightly divide the majority so better control.

So basically, the same pattern that history teaches.
