Idiotic Prejudiced theater Teacher

My theater teacher is one of the most idiotic prejudiced men i have ever met!!!! my God i didn't know such an idiot existed!!!! Ok here's what happened. In theater class we have to do this stupid shit play thing or whatever and he told us to find five African-American Females ( this is an all black class, by the way) because he didn't think any of us could 'play white', and of course, me being my racially proud self had to take him to the woodshed for saying something so racially insensitive. I mean, come on now, you have a class full of women of african descent but you say something that blatantly racist. I asked him verbatim how do you play white? like what's the difference between playing white and black??? i mean people have done shit in blackface for so long its about damn time. we should be able to play anyone we want. to which he responded 'blah blah blippity blah blah blah shit blah'
