The one thing I can't stand, and think is unfair, is when a few bad apples ruin a decentralized movement for everyone. BLM had the exact same problem, idiots delegitimizing a movement fighting a very legitimate problem, and then those scattered incidents being collected to allow organized detractors to mischaracterize them.
Now we're seeing that happen with the rightwing protests as well. Don't get me wrong, I hate nazis and also do not at all agree with Trump supporters / people that want to keep the confederate status, but they're not all nazis.
