They really don't. You think that Trump's followers all believe that Trump will give them everything they want- that they're a secular messianic movement. This is wrong. It has, over the past couple of months, become increasingly clear to me that a significant number of Trump's followers, both on this site and elsewhere, are a death cult. They don't want or expect Trump to do anything good for them, and in fact desire Trump to do things that will directly make their lives worse, such as inciting a civil war. The bloodshed, carnage, and civil strife that would result from Trump "crossing the Rubicon" is not an unfortunate price to pay, but the end goal. The version of the future that they see in their heads fills them with so much despair and rage that, in this moment, they'd rather see the entire world burn to ashes than face it. That's why they are advocating for civil war, drone or atomic strikes on China, domestic terrorism, etc.: they fully believe the hype of "the other party is the embodiment of evil and their victory dooms mankind forever".
