I'm not saying that I didn't see racist shit, because I did. But a slave auction just goes well beyond anything that I ever saw. My family is from Mississippi, so yeah, I heard some racist stuff. I was born there, but my parents moved away just about right after I was born. I've lived all over when I was a kid. West Texas (Midland/Odessa area), Georgetown, Jarrell, Blytheville AR, Richmond VA, Chicago (twice), St. Louis, and then down to Sugar Land starting in my sophomore year of high school. To be honest, with all the moving we did, I never made close friends until I got to the Houston area. Even then I was horribly shy. I was also younger than everyone by a full year, and to top it off I was a runt until my sophomore year. I just never really ran with the 'popular' crowd, so I guess I was extremely sheltered.
Freshman year of high school I was living in St. Louis out in the suburbs. At that time they were busing inner city kids out to our school. For the most part things were okay, but there was definitely some tension. At wrestling practice one day we were running sprints in this really long hallway. Half the team was on one side of hall and the other half was on the opposite side. 2 kids would sprint down the middle and get back in line. One of the inner city kids, who was our heavyweight, got to the end and accidentally bumped into this white kid. The white kid went straight to "you dumb" n word. Everyone got quiet and I fully expected the inner city kid to just beat the shit of him. But he didn't, he just kept quiet and didn't even acknowledge it. I know he heard it, but I'm sure that he had been warned of stuff like that by his parents and was told to just let it go. To this day I have no idea how he kept himself from beating the shit out of that kid.
Long way to say that just because I wasn't aware of really overt and publicly racist shit going on, doesn't mean that it wasn't there. I probably just didn't know about it because I didn't really hang out with a lot of people because I was not popular at all and was extremely shy.
