One comment I saw eons ago explained it, it went something like this

“Imagine theres a group called Team-No-Bad-Guy. They gather to yell to stop people doing bad guy things. You don’t like those people that they yell at, but you don’t like the non-yelling methods Team-No-Bad-Guy uses sometimes. Team-No-Bad-Guy hears you say this and calls you a bad guy and begin yelling at you. You realize that they can call anyone bad guys and you wonder how things would be for you after the big bad guys were gone.”
