Im very 50/50 about this. If you have never laughed at anything offensive, someone being rude to someone , someone making fun of someone in any way then you could be mad and you should break things off and find someone whos the same. BUT Many people would laugh at a someone else whether its rude laughing or just simply laughing cause it was funny no one is perfect, the difference comes in when you know the person personally. Lets just show this scenerio lets say i have a team mate on a video game who barely had kills, im calling them ass, but if its a friend im gonna say nice try, we'll get em next time.
