The only political power you have within America’s political system electoralism is a game of chicken wherein you withhold your vote unless change occurs. If you’re mad at people saying they won’t vote for Biden, I urge you to direct your energy at Biden and the DNC.
There are other avenues to change, but they get your head bashed in by cops, so I’m confident the people tut-tutting about voting will never get involved at that level. Must feel great to ignore the devastating impact of American foreign policy just because it doesn’t happen near you!
