The real issue is, Voting DOES fix things.
But not "everything instantly."
But not voting, or voting for fascists, absolutely will never fix anything.
Like Democrats are a shit ass garbage party, but there is ZERO path to any actual change and progression through the GOP. And it will probably take decades of actual effort, but people are stupid and lazy and want instant gratification. So when Dems do garbage they roll back to not voting or supporting fascists who do nothing but lie.
