You are correct it has nothing to do with race. But you are incorrect that it has everything to do with a lack of discipline in schools...........the lack of discipline comes from the parents.
I think you're wrong. My (admittedly more or less adult) friends go through a remarkable language transformation when their parents or other authority figures are around. And I rarely hear kids with parents in earshot using the major baddies, at least. It's always when they're just with each other.
I wouldn't necessarily blame the schools (although I wish they'd use the soap treatment!) but negative peer pressure.
While I mostly agree with you, the vast success of the athiest liberals of injecting their secular values (or lack thereof) into the public school system makes it an environment where kids of very good, disciplining parents are going to be exposed to the garbage that our liberal friends love so much.

At my daughter's 8th birthday party, about 16 girls were seated along a huge table, painting crafts. While I was helping the girls at one end of the table, my husband was down at the other end. After the party, he told me that one of the little girls uttered the f-word in a normal tone, after spilling a bit of paint on her artwork. My husband said that when he looked over to where the word came from, all the girls around her were staring at her with that, "I cannot believe you just said that/you are going to get into big trouble" look. My husband then scooted over next to her, made her look into his eyes, and he firmly told her that her choice of words was unacceptable. And, if she used that word again at the party, he would call her mother to come and get her.
This child is the daughter of (this I found out later that evening) a very well-known surgeon, who was on trial in our area after being accused of raping several of his patients. His wife has stood by him, although with a mouth like the one on their eight year old, it's easy for the mind to wander and wonder what that home has been like during the midst of their legal proceedings.
Sad and disgusting.
Parents can discipline as much as they want. The control they have at home is complete, BUT when the child goes out into society and is faced with vulgarity as the norm it undermines what good parents are trying to teach.
I banned MTV in my home pretty much from it's inception. My daughter survived without it, but that does not mean she did not see it at friend's homes.
Movies, Cable TV, Music, Video games... all of these contribute to a coarsening of our culture. Like it or not it's not just about the parents.
