Amid mounting protests, college clothier Abercrombie & Fitch on Thursday said it will pull a line of T-shirts from stores nationwide following complaints that they depicted racist caricatures of Asian Americans. The $25 T-shirts show cartoonish Asian characters with slanted eyes and conical hats who serve as pitchmen for fabricated companies such as restaurants, dry cleaners and bowling alleys.One portrays a man pulling a rickshaw with the words ‘‘Rick Shaw’s Hoagies and Grinders. Order by the foot. Good meat. Quick feet.’’ Another shows two Asian men at ‘‘Wong Brothers Laundry Service’’ and carries the logo ‘‘Two Wongs Can Make it White’’A&F, which markets shorts, T-shirts and other casual apparel to youths between the ages of 18 and 22, said it made the decision after receiving ‘‘hundreds and hundreds’’ of complaints about the T-shirts. The items have been on the shelves for two weeks, but the firestorm hit within the past couple of days, mostly a result of rapid-fire e-mails to dozens of people at once. ‘‘It’s not our intention to offend anyone. The designs were supposed to add humour and levity to our fashion line,’’ A&F officials said.
