I strongly suspect they may have sponsored a college club that printed the tee shirts. Somehow I don't see them endorsing this and the money is damage control. I was in a 'black' sorority with a girl who was a carbon copy of Sister Souljah. She idolized her too. It's actually pathetic really. She talked about how much she hated white people. In fact, she had joined the sorority hoping to get away from annoying white girls. When I pointed out once in a debate if there is institutionalized racism why do many black foreigners come and be successes where Americans fail? I got this response(((crickets))) right before the name calling ensued.
Those type of people are striving for percieved power and identity with racist organizations. It's easy to hate other folks, it takes no intelligence and it takes no skill. Whereas in the business world, accounting and management are required, in athletics strength and endurance are required, in politics strategy and personality are necessary, and so on.
The fact their racist beliefs fall apart in the face of truth means nothing to them. In their warped ideaology, they are supreme and powerful.
It so much energy to hate and these people eventually burn-out and become miserable wretches.
