Anyone can say any word, its just a word at the end of the day, someone can say mother fucker to you, what you gonna do ? train your mind to take insults without reacting to them, you should not react to words or ideas compulsively or emotionally, they are only as real as you make them, how can a word bring you pain. Remove yourself from the people who are casting slurs on you, defend yourself with counter slurs, they might beat you up doe. You also have the choice to beat them more lol.
grow up !
