Input: Text: this happened friday

so, in pre-ap we had an athens-sparta debate (go sparta), and during the debate, the athenians said that "making technology for war causes more war" so i respond by saying "really? ever since ww2, there have been no wars -- (i get cut off here) the class is now flipping shit, calling me retarded, autistic, and stupid. the teacher tries to now explain to me how there have been multiple wars since ww2. i know this. i'm not a dumbfuck. i was trying to say there had been no wars using nuclear weapons since ww2. i know this quite well. my family has fought in every single one of those wars. but seriously? why not let me finish my fucking sentence? 

so after she lets me finish, half of my class tells me to leave, the other half to go back to athens, and then the teacher is still calling me stupid.
