I can agree with some of the concept here but think there needs to be a little bit of focus here. I live in California - it didn't vote as blue as I would have liked but it is still clearly blue. My city was largely blue. What would stopping my contribution to local food bank do? For one it's hurting the people that, at least in my community, are not responsible for our national government. In addition, their suffering is essentially invisible to those with money and power. They wouldn't care if there was starvation due to tariffs / inflation.
Women's health - I am more conflicted there. I don't think I'd be able to persuade my wife to stop PP donation if I tried. I get that white women need to experience some of the real impact that loss of reproductive freedom would have but again, white women aren't really why we have the national government we do.
Local help is still necessary and good. Voting for things like rural broadband (or shit, anything rural)? Fuck 'em. Lobbying for Gaza / supporting student encampments? Fuck 'em. Not sure what else withdrawing support would do to actually impact those who are responsible.
