You an check out this site below and see the other shirts they have.
Although this is different from having Abercrombie and Fitch selling them because with their history according the the "Abercrombie & Glitch Article," they do not have the best reputation respecting other people. I don't really find it hard to believe that they didn't know that this was offensive since they do not have the greatest track record. For example, they only want a certain "look" when it comes to their employees and they do not even make any plus sized clothing because their brands only targets specific communities.
