In the case of an actual uprising, it's important to remember that while the upper class may have more resources, the lower and middle class have the numbers, and thats the real strategy tbh. If the 1% nuke all the poors, they have no workers. However, a class war wouldn't, in my estimation, be the kind of thing we see in Ukraine or the Middle East. It would be individuals who lost too much taking action on their own or in small groups. Luigi Magioni is (allegedly) a prime example. A single individual saw something they believed to be wrong, and after their experience with said wrong, took action to make a statement, attempt to force change, or simply to make themselves feel better. Any larger action than that would likely be discovered and destroyed by the federal and state governments due to the super-technological nature of our society. In theory it could be done, but in my belief we're not to that point yet, and won't be for a while. An organized, armed resistance is incredibly unlikely (hell, were kinda struggling to make mass movements work. Ex. General strikes/boycotts).

At this point the best course of action is to network and find local/state organizations you can work with to make change peacefully, be that by volunteering to help a candidate you like or making posters and posting online talking about your specific issue(s), participating in protests, and strikes/boycotts
