It’s exactly like democracy;
You start out with something you dislike. Then you have options of things that are also awful, but maybe you’ll dislike differently. You get to pick. Or not. Most people don’t participate anyhow - also like democracy.
Show me where on a ballot I get to vote against a candidate… You can either vote for someone, or not.
Anyhow, it creates the illusion of choice, just like democracy. You can chose any of 1000 kinds of breakfast cereal, but when it comes to important things, you just get to choose between two things that are differently awful.
