I wish I never learned about racism and slavery in school, do you agree?

Do you ever wonder why racism still exists in out world. The problem is that too many people are holding onto the past and not letting it go. I am not racist, but I do feel like I have to act different around African Americans than Caucasians because there are a lot more sensitive conversation topics surrounding minorities. For example, if I say, "I'm voting for McCain," an African American might immediately ume I'm a racist, or if I say, "I just got a promotion at work, an African American might say, "That only happened because your white." (Both those examples actually happened to me). I just feel like there is so much unnecessary tension between Blacks and Whites and I can't stand it anymore. I know what I'm about to say is a little cliche but I JUST WANT ALL OF US TO BE TREATED EQUAL!!!!!!!!!!!!!!! Growing up, we were all taught in school all about how blacks used to be looked down upon and treated as slaves and whites were (in charge) of everything; From a psychological standpoint, I believe that set many people ahead of time to be "set up" for pre-meditated racism because schools were teaching us that we were different. I honestly believe that if we never learned about slavery or racism in school, most racist people today would have never become racist because they would have nothing to base one race superior over another race. This is what I believe. Do you agree with my hypothesis? Think about it, if my theory isn't true than that just means that Whites biologically feel superior than blacks (which MOST will probably agree ISN'T true).. what do you think?
