MILWAUKEE - An American soldier in Iraq who e-mailed a U.S. company to ask for a shipment of floor mats got a brusque reply: "We would NEVER ship to Iraq. If you were sensible, you and your troops would pull out of Iraq." The response quickly circulated on the Internet and led to threats against the Muslim-owned business, including demands for a boycott. Bargain Suppliers, an online retailer, shut down its Web site Monday and fired the unidentified employee who sent the e-mail, television station WTMJ reported.
