How to deal with racist peeps on internet?

As per we already know communication is so easy now as compare to ancient times. But theirs a backdrop to that their are some peeps who are bad (racist).
They don't really have manners to talk to person on other screen side like.. whats their problem. Here we try to be nice but they be like..(not to mention guess you get it)
Don't get me wrong if any racist is reading this right now please be polite while talking to peep from other side of screen because you never knew what that person might be going through.
Because their are some peeps who used internet for make new friends but that racist behaviour make them regret making new friends resulting making them bad (racist) person too
