Racism Towards My Sister

my sister was cycling today with her friend and some racist said to her: ‘buy a bicycle next time, okay?’ to her and she came home and told it to me. racism has to fucking stop. this made me fucking angry. u guys have to stop being racist and fucking stop insult people cuz of their religion. i know 10000 christian insults, so stop it. or we will start insult u back. we havent insulted back cuz we showed respect. but enough is enough. one more insult and ur gonna get fucked up.  im a gangster
