Why do some people say that Carribean Women (West Indian Women) are..?

Mean, crazy, easily-enraged, jealous women that likes to start fights. I hear alot of people saying that. I'm half Trinidadian (dad's side) and I don't get it at all. I'm only hot-tempered when someone messes with me. My mom is African American, she's hot-headed when she's messed with, so I don't know how this is a "West Indian" thing.
