around 1980, at the famed Yale Political Union-a debate was sponsored and it featured -one side, Roy Innis, the leader of the Congress of Racial Equality and on the other side-Professor Ernest Van den Haag

the topic was affirmative action at schools such as Yale with Innis supporting it, and Van Den Haag opposing it. Shortly before the debate started-the black law student organization-including Anita Hill, tried to prevent the debate by picketing the Union's meeting house. It was unsuccessful-most students ignored the childish picketers, the speaker of the Union-invited several of the picketers in and told them they could speak ahead of the student members. They refused to do so-saying their status at Yale Law was "not debatable. Even Mr Innis found that claim lacking credit, and Van Den Haag used the failure to debate rather effectively. So this sort of nonsense has been going on for decades
