What voting for Biden will accomplish is preventing Trump from entering office and all of my rights from being stripped away, and that is very important to me.
Your take seems to be “I’m so leftist I refuse to vote because voting is pointless.” If that’s correct, then I’m going to choose to believe you’re a right wing troll who’s trying to convince me not to vote so your candidate will win, because that’s easier than believing that anyone on Earth is so far up their own ass that they’ve convinced themselves that doing nothing and letting the world get worse on its own is the best political statement they can make.
