Howling:Is the Master a racist

I was just wondering about the sound of drums when the master makes a pretty horrible comment to Martha and Jack. Was he meant to be racist I mean I assumed it was because he bassically calls Martha  a freak and jack a girl but I added that to his character page and someone took it off literally a second later so have I misread that was he meant to be joking or just trying to rile the Doctor or something does anyone know if RTD meant to add that to his character with that or if it was just as I said a joke. Its a pretty big thing to add to his character he never seemed prejudiced before LOL Physcopath murderer but not prejudiced. Winehousefan, 19:40, July 16 2010 [UTC
