I don't think that's why they support anyone. Nobody really understands all that.
It's tribalism.
They don't even know or care who they support. As long as it spreads fear.
There's no other reason why Trump won, even when almost every pundit predicted that Clinton would win, and that Trump himself did not expect to win. It gets even weirder when one realizes that Trump was not only a supporter of the Democrats for years he was also a family friend of the Clintons.
But that's nothing compared to every point I raised in my earlier post when I explained the two terms that you did not recognize. But I get this feeling that you at least recognize the examples: blatant attacks on Iraq and Afghanistan over oil and minerals, part of a very long history of warmongering, lots of benefits favoring the rich and leading to the 2008 crash that anyone old enough would have recognized easily, and more.
It doesn't take much to connect all that to politicians working for the rich, and even to 9/11.
