To translate El_Criollo's message in a more positive manner, Aysha;
Exercise the same universal pre-cautions that you would exercise in any big, poor, urban setting. If you know how to behave in, say for example, NYC, Lawrence - Massachussets, Jersey City, NJ or Washington, DC; then you will be just fine.
Be yourself, who cares what others think and remember the only hatred one really needs to fear is self-hatred. I read a lot of self-hatred on the boards of this website.
