Persian doesn't cover the hole lot of them, it doesn't cover Arabs & Muslims and/or vis-versa, you cant use terms like sand-******* to describe them because that is offensive, I think a good politically correct term would be Mud People, as it is not offensive, so when you issue a warning to the hole lot of them, they will understand the definition as it profiles all silly Mud People that when get striked by a bullet, they start shouting:
Ha,le,le,le,le,le,le,le,le,le,le,le,le,le,le,le
And also manage to slap them selves in the face as they bleed to death, I believe that only Mud People have attained this skill, and when you use the term Mud People, everyone including Mud People will understand and know who you are talking about.
