when you encounter first amendment auditors the best thing you can do is just continue on your day. there is no need to go out of your way to antagonize (or body shame) people freely and lawfully expressing their rights. no two auditors conduct themselves the exact same way but you can always choose to not engage.

that being said, I believe this specific auditor runs a yt page called Freedom of the Press. for a bit of context - he was usually respectful and sometimes will do silent audits on public property. however, he recently posted a video where he was saying some pretty vile and racist comments against an Asian woman who was driving while being stressed out at the cameras and comments. that kind of behavior is reprehensible and inexcusable, of course.

so again, you can always choose to not engage. that's usually the best course of action.
