No, I fully believe that populations are controlled through 'propaganda' and 'education'. In the case of racism, the "skin color" meme is one of the beliefs they instil in their victims.

Let me ask you, do you believe there's no difference in dog breeds? "Dude, fur color makes no difference!" In fact, different breeds and variations across all animal species have very different characteristics and abilities. Human beings are animals. There are very distinctive variations between human "races", which are both well documented, and discernable in everyday life.

So while I do believe that people have different characteristics and abilities, many of us have the ability to learn new information, and/or correct misinformation that's been installed in us.
