Despite everything, if you're in the US, you should still vote
(lemmy.blahaj.zone)
When given a choice between a millitary industrial neoliberal with a rainbow voting base and a fascist who is one elon musk golf session away from banning HRT, the best option is certainly not to refuse to play out of protest
At local level. Organize school board, dog catcher, judges, city council, planing commission, library board, community college board, do what the right wing does
This is really key, though the state level is probably most important. If your voting activism doesn't go beyond the presidential election, it's performative at most. A third party candidate without members of their party is state houses and Congress is going to be fairly ineffective even if they somehow did do the impossible and get elected.
Maybe with just a little less cross burning, lynching, and religious extremism.
