BBT not racist?
I have to comment on this because I haven't seen it discussed yet, and if it has then please excuse me. I got the impression from the film that Billy Bob's character wasn't actually a racist. There are 2 instances in which we see him act in a racist way in the film: the first is when the neighbor boys come over and he fires his gun, and the second is when he is beating up his son and calls one of his coworkers a racial slur.
The first display of racism is only after his father nags him to the point where he can't finish his meal in peace. To me, his body language and his response said to me that his racist display was a means of placating his father, especially after his father commented about BBT's mother.
The second display is when he is in a highly emotional manner. He was beating up his son. The black guard just happened to be the one to grab him and unfortunately he was an easy target for misdirected anger. He was trying to cut somebody deeply and emotionally and that guard got a verbal lashing because BBT could no longer physically harm anyone.
I just thought of his character as a miserable person. He was mean to those close to him, and living in the south black people were an easy scapegoat for a pathetic and unhappy man who really hated himself. That's just my thoughts, I am open to discussion.
PS
I am a black female living in the south, so I have definitely had my run ins with racism, I just don't think that his character held racist views, it was just the path of least resistance in his household.
