Hi there,
a lot of them are taught from the very beginning that we are bad, that's why. I lived in the Middle East for a couple of years, and a lot of people there are brain-washed.
Because Americans want to force their culture and values on everyone else. Because if you read Coca Cola in reverse, it reads in Arabic: No Mohamed, No Mekka. Because America support Israel and turns a blind eye on the suffering of the Palestinians. Because there are American soldiers on Saudi soil, and because of the support of the hated Saudi king and his regime.
ignorance jealousy indocrination
it is not just the middle eastern muslim hating americans
ALL the muslims hate all westerners
disclaimer...
OBVIOUSLY there are a few individual exceptions BUT
bombs, drones, etc
