Some of the stimuli are phrases like "Tell me what democracy looks like, this is what democracy looks like" Or "hey hey, hey ho, [insert name] has got to go" or "black lives matter"

Physical stimuli is groups of people wearing black masks or handmaids tale outfits. You can't change any ones mind when they are present. If you get close to changing a mind, someone will walk up to them and say "don't talk to them" and they leave, just like that.
