You learn very young growing up in NYC to size them up. It doesn't matter their race. You learn to trust your gut instinct. I grew up in Manhattan among all races and ethnicities of men young and old. I knew all my neighbors in all the areas of lived in. Some were trustworth. and others weren't. I learned it had nothing to do with race but with the individual man.
I feel the same living in Florida now as an old lady. There are old men that I would never want to be alone with. In fact, there is one of my neighbors in this very white gated community that I will never talk to or EVER open my door to. He gives me the creeps.
I trust my NYC born and bred instinct over any "profiling".
