I believe you were either too stupid to realise the real message behind the ad or clouded by your myopic judgemental lense. Let me break it down in case you missed it.
The ad just says no matter who we are, who we identify as, if we throw all those out the window given the right conditions, we find out that we are humans first, good natured and have a common ground that we can all relate as friends. Our perceptions that black, white, Muslim, Christian, gay, transgender etc is bad is not something we are born with, but something we pick along the way and develop a strong hatred for.
You can’t tag people as being stupid because you were too stupid to understand it
