Who’s stupid enough to hold an anti-Trump rally anyway? What’s the upside there?
Are you trying to convince Trump supporters that they’re assholes and you’re offended? They’ll be proud of that. They want that.
Are you trying to bolster Trump’s message that liberals are trying to silence him because he’s telling hard truths? Good job, you played into his message.
Are you trying to make the mistreatment of people at his rallies not seem so bad by giving the impression that there are troublemakers that attend them? Great.
There’s no upside to it. You’re not going to gain anything by doing it. You can only lose. Why the fuck would you do it?
