Teacher's 'terrorist' joke no laughing matter for student

Well when I throw my drink back in the window and call them niggers it is not because I think my race is in any way better than them it is because they are the epitome of their racial stereotypes.

My whole point in this is that the word racism, just as is fascism is used much too often and by far too many that do not understand what it means.

No you cannot simply redefine it to include bigotry, prejudice, discrimination, why do'n we just let those words do their jobs.
