I agree 100 percent.
I've been going to a Haitian Ballroom studio, and have been dealing with the Haitiian men/dancers for over 2 years.
I've seen that happening, and I've seen them mistreating their ladies, and aslo cheating on them. I have been yelled at, gossiped about, etc. by my Haitian instructor.
I've spent a lot of money learning how to dance, and in most cases would leave the studio in tears because of the instructor's psychological abuse.
Anyways, I stopped going there, found better places to dance at, where most of the men are white, and dance with me a lot, treat me well and make me smile, not cry.
