I dont know I should cautious towards Black people?

Be cautious of everyone. Black doesn't really have anything to do with being ually hared. That is something that men from all races do. Even women have been known to do that to men. Many people are out to get you, take everything they can from you. What I especially hate are people who get rich off of human suffering and misery. There is always someone trying to steal from you, either illegally or just legally robbing us. This is definitely a dog eat dog world. Smiling faces sometimes tell lies. Bewarrrre, until you really get to know anyone.
