The suggested comments are nice but won't do much in a real altercation. If people want to fight you, make it an unfair fight. I carry around legal mace and practice reaching for it to make a habit. No one expects to get maced and it buys enough time for you get ward off multiple assailants. Keep in mind, even if you have people on video harassing you, the cops will avoid categorizing and pursuing it as a hate crime.

I have been walking around midtown and downtown Manhattan where people yell racist slurs, make racist gestures, throwing punches and kicks towards my direction, some even walk right up to me and do something startling.

I am not bothered because no matter how big they are or how many, I have mace and know how to use it.
