How would you respond or react when someone calls you a racial slur without getting physical or being a coward?

call them a racial slur back, only cowards get physical cuz someone said a word, u have no right to touch anyone, its there right to say whatever they want. either ignore them or call them a racial slur back. if hes black call him n word, if hes white call him butter looking welfare trash, if hes hispanic call him illegal immigrant, if they are middle eastern or india call them binladin. if they are chiniese say i feel sorry your da only race with wierd eyes and nose no wonder ppl dont like you. every race has something that they can be offended.
