Well, you should look at how Arabs are portrayed in mainstream hollywood movies. And then try to find out what this means and what effects it has.
it's brainwashing.
A book was written on it. There are almost no Arab children. You never see arabs that play with their children. You never see an arab couple that love each other. You never see normal arabs. They are always bad guys, stupid and unreliable.
Dr. Jack G. Shaheen did 20 years of research on it and then wrote a book and made a documentary. Both are called: ' Reel Bad Arabs: How Hollywood Vilifies a People'.
This has been so for ever. Aladdin is a good example. This is how the opening song starts:
"Oh I come from a land, from a faraway place
Where the caravan camels roam
Where they cut off your ear
If they don't like your face
It's barbaric, but hey, it's home"
They changed it later.
Most stereotypes and bad guys are cyclical. But not the arabs.
So arabs aren't people. Just like the Jews during 1938-1945. You need to dehumanize people to be able to slaughter them as animals.
