What is your definition of “meaningful political action”? Picking up guns? Got news for you, the government has more of them.
Do you really think the two options for politics are voting in sham elections and WACO?
Voting starts at the local level. You vote people into local city government who reflect your views and values. Those people often enough have greater aspirations and want to move up in the political machine. It’s extremely rare for someone to be vaulted from average Joe to major political player in one leap. Trump was able to do it by being a populist piece of shit who could pay his way into office.
You have to start small. Get your city council to look like you, then move on to the county, the state, etc.
Local elections are also pretty much a “which landlord can pay the most money and be the least repulsive”
You have to build parallel power structures before you can meaningfully influence any electoral structure, including local ones.
