This is bad because?
Making blanket statement about a race is wrong. I know lots of Arabs and they certainly are not the "dirtiest, smelliest people ever to infect Gods Earth." and I can tell 'where an Arab ends and his camel begins'. Granted there are lots of radical Muslim Arabs who are sorry excuses for human beings, mostly because of their extremists beliefs. But you cross the line when you say all Arabs are that way.
