Why are alt-right politicians becoming more popular?

I think that this is a very complicated topic. It might be because people are craving change. A change for something better. They associate past governments with not being able to appeal to their expectations, so they decide to choose alternative ways. Something that they have never tried before. Sometimes, in countries like Brazil, which are on the verge of collapse, people might realize that the only way to fix their country is by using force, which in a way makes sense. We need to remember that the people decide to elect these politicians. It's their decisions and what the majority considers good.
