And Iran people come in Europe wearing something they musn't.
Logical Fallacy of the day: Hasty Generalization
Your statement assumes and genralizes that most Arabian refugees going to Europe are from Iran. In truth, hardly any come from Iran. Most refugees in Europe are from Syria.
Your statement assumes that Iran == all of Arabia/Middle East. Well, I am sorry to disappoint you, but there also exists Iraq, Syria, Turkey, Jordan, Lebanon, Israel, Kuwait, Saudi Arabia, Yemen, Oman, United Arab Ermiates, Bahrain, Afghanistan, and Pakistan. Armenia, Georgia, Azerbaijan, and Egypt may also be considered parts of the Middle East as Well.
