If you support candidates and issues that lose, you’re not a progressive. You’re a conservative.
Jill Stein is not a progressive. Why? She doesn’t make progress. She confuses holding an opinion for making progress. She’s convinced many people to hold opinions in higher esteem than making progress.
To the degree that one holds opinion in higher esteem than progress, and thereby aids conservative ideas to win, then that person is working for the conservative movement.
Progress trumps opinion. A progressive understands this.
