I'm going to scold a guy at a bar for being ignorant and having no game
What is so bad about his behavior?
Nothing, I just want to put him down.
Have you considered making a joke with them rather than scolding them?
I'm doing it for the black lives matter movement.
No matter what the reason, you shouldn't draw attention or pick a fight in public. If they are talking negatively about something like the BLM movement, tell the bartender or security guard and they'll keep an eye on the person.
