staircase upon tangled staircase

what should have happened:

teacher: white people are brought up to hate black people. it's ingrained in their heads from birth.
(unanimous approval--jeers of "that's right" and "uh-huh" across the room)
me: wow. is it just me. or was that kind of racist?
teacher: what do you mean?
me: you're saying that all white people are raised to hate black people, right?
teacher: no, but--a majority--.
me: yeah, well, that's a stereotype.
teacher: no, it's not.
me: then it's a generalization?
teacher: yeah. wait--.
me: and what's the difference, in your opinion?
teacher: well, a stereotype is like a generalization, but it's a negative generalization about a large group--.
me: ok. so, saying that all white people hate black people is a good thing?
teacher: no, it's not. not at all. it's a bad thing--.
me: ok. here's the deal. not all white people hate black people. maybe some do. but not all. to lump the haters in with everyone else--you're making a stereotype--a negative generalization about a large group of people. a race of people.
teacher: well, a good majority--.
me: how do you know that?
teacher: look around you--racism is still an issue in this country.
me: we just elected a black man as president. we, as a country, a predominately white country, elected a black man as our leader. true, racism may still be an issue. but, white people make up the majority in this country--so, how can a race of people, who you claim are raised to hate black people, elect a black man into office? how is that possible? you're perpetuating stereotypes and, even worse, perpetuating racism by trying to combat it with even more racism. it's not a logical argument.
teacher: well, i still stand by what i said: most white people hate blacks.
me: really, though? really? most white people? do you have evidence, statistics? where is this coming from? anecdotal authority?
teacher: it's obvious--just look at the programs we watch on television, look at the--
me: you're an idiot.
teacher: because i'm black and proud of it?
me: no. because you're a person--an individual--with some messed up ideas. you say idiot things and you believe in idiot things. you show all the signs of being an idiot. therefore, you're an idiot.
teacher: get out of my classroom.
me: and you're a racist.
teacher: get out.
me: know what i mean, jelly bean?
teacher: now!

how it really went:

teacher: white people are brought up to hate black people.
me:(internal outrage)
class: yeah!
