Also, it's ridiculous for someone to think that every "Both sides suck" posts are bought and paid for propaganda. Some may be. I'd be surprised if it didn't happen sometimes. But, the majority are probably just understandably frustrated people.
We shouldn't be policing people's expression of frustration with the system. If someone can't express frustration without being told they're a shill or a propagandist, they're not suddenly going to become an engaged happy partisan. Instead, they're probably just going to get even more disillusioned with the process and will stop talking about it and maybe stop voting altogether.
The democratic party sucks. It bends over backwards to help out corporate interests. It's more interested in winning the next election cycle than it is in making important changes. It often goes wherever the wind blows without having any conviction.
OTOH, the republicans are much worse. They're hell bent on enacting racist and sexist policies that will ensure straight, white, christian men remain in power. They're currently led by an absolute moron who's by far the most corrupt person I've ever seen in my life.
So, the options are currently between a status quo party that might not make your life better, vs a party led by a chaos gremlin which will systematically destroy everything within its reach. Voting for the lesser of two evils may be annoying, but it's often important.
