Your wrong, latin women love that sort of aggressive behaviour.
You need to look at the video. And see that when he got up to dance, he put his hands on her ass, she moved them UP, indicating that she wasn't comfortable with is hands on her ass. And it doesn't matter if the woman is Latin or not, it's individual. You can't assume things because of their ethnicity. A chick may feel comfortable with one man but not with you. She may be a freak with one man and not with you.
You can't say, "well you are Brazilian so you like it!"
or "You are black so you are a whore." that's just pure ignorance.
And they are dancers. Take a look at the vid @2:50-2:56
