In great part, you are right. But the heart of it lies in the vision of 'us versus them'.
Crips vs bloods. Whites vs blacks. X team supporters vs y team supporters. This religion vs that.
It is the view of others as the alien other that allows us to put aside what makes us human; empathy.
The elites rule by dividing and conquering. They rule because fools such as yourself view these divisions as very real.
Now, I will admit, it is a bad idea to allow uneducated people (regardless of race or religion) into a country which is bombing the people these uneducated people view as 'us'. But that is a very big difference from stating 'they are evil/lesser' because of religion or race. One is a rational view, the other is an emotive view fueled by propaganda.
