Idk what's worse: not voting and making your voice useless out of apathy or laziness, or voting third party and making sure your voice means nothing on purpose.
The whole point of a democracy is people speak their minds, is it not?
If you vote third party, your vote is an extension of your true self. If you vote for a potential winner just out of the likeliness they'll win, is that really "you"?
Same logic if you don't vote. In Australia, voting is a requirement for all citizens, and it's disastrous because you end up with people who just don't care filling up some random candidate's score, so the outcome doesn't reflect what people actually want.
