You want to know how sane people believe in crazy things? It's the same way that people get drawn into cults.
It's the power of supporting your group. Why Cubs fans are (were) loyal to their team, even if they were losing. Why cops will protect their own, even if they are crooked. It is a virtue in evolutionary terms, since groups are stronger than individuals. So those who support their group are stronger..
But then,
as P.Z. Myers explains it when talking about how the "America First" group started acting like a cult, it can be used to manipulate people into believing crazy things...
“[Members act so] racist and ridiculous in public that it ruins people’s lives,” said co-host Kelly Weill on the podcast. “You can’t go and get a normal job after that, so they turn further and further into this movement, which really does function almost like a cult.”
"The fact that Gosar and Greene, who have a modicum of power and influence, are entangled with Nick Fuentes, is revealing about the sad state of American politics. How can anyone in the halls of power take this guy seriously?"
That last paragraph, though, explains a lot. America First is openly and loudly racist, and its members have openly slapped that stigma on their records. This is how cults start: throw out one absurdity for your followers to accept, watch as the majority walk away, but the ones who stay…give ’em another absurdity. Then another. And another. You’ve got the few so deeply hooked that you can get them to do whatever you want. ... Fuentes is such a patently hateful fool that his followers have to be committed to stick by him, not by virtue of the quality of his arguments, but because they’re so stupid that admitting that leads to an exposure of their gullibility.
You convince them of extreme views in order for them to belong to the group, which isolates them from others, so that they have no other group they can belong to. Which ties them closer to the group. Then they have to accept even more extreme views, tying them closer. A vicious feedback loop that can make (some) people, especially those who are already isolated and need a group, believe ridiculous things. They have to believe because they have no place else to go.
When the group becomes your life, it doesn't matter what the group believes. You have to believe it, or you lose everything.
