I'm guessing that the video is just there to get people thinking as it is obviously a comedy act. In regards to 'How Not to Be Racist' I would say that's it's pretty much impossible not to be racist. Now before you go slamming your keyboard saying how wrong I am, hear me out. People can do the things mentioned in the video, they can respect people's heritages and their ethnicity. Heck I call all my my 'black' friends African American. However, there's one factor of racism that cannot be stopped: Subconscious Racism. Our subconscious minds process information all the time and that information comes out whether we like it or not. This Subconscious Racism manifests itself most often as in-group and out-group bias. Take a look at psychologist Piliavin's Subway Study in which they had people wearing the same clothes and preforming the same actions fall down with the only difference being the person's race. People who were of the same race as the person who fell would be more inclined to help them. They never thought to themselves "Oh a [insert race] I don't wanna touch them they [insert racist remark]."

Plain and simply, you can try as hard as you want to not be racist but subconsciously you will be and there's nothing you can do to fix that. It's just something hardwired into our brains from generations ago.
