The 20 black people who live in my town are probably not going to be a problem. As a matter of fact, they are more polite than the white kids.
When I worked in the high school football concession stand, the black kids always called me “sir” and said “thank you”.
I substitute taught for a few months in SE Georgia after I retired. I remember one really large Black kid who looked like he was beefed up on steroids on the football field.
He never gave me any trouble. Once he was acting up a little and I told him to go sit in another chair which he immediately did without protest.
A few weeks after school ended and just before I left that area, he murdered a little 18 year old White girl who was the mother of a six month old baby. Yes she was married. He did this while robbing a video store. No reason at all to kill her. I just did not know him at all. I would never have guessed he would have done that.
Then again, I've seen southern blacks kicking my college roommate's head in, and I've had a southern black stick a gun in my face.
Never had a white person do either.
