Aside from the fact that someone such as yourself (who clearly is not involved in historical research at all) is nevertheless acting like a pretentious snot, I shall "try again."
In historical research, there is such a thing as a timeline. Enough time has to pass before any discussion of merit or demerit can take place. Depending upon when said course took place, you could approach the question in a limited manner. More than likely, since it started roughly in the late 1970s, not enough time has passed. Furthermore, the debate is very much a matter of current events, rather than history. Furthermore, most historians, suffice it to say, are not well-versed in science to make a defense. This is likewise a problem for a historical student to become an expert in theoretical science and expected to approach it from either way. This is why, for instance, historians interested in the Environmental Movement (which was bourgeoning in the 1970s) tend to shy away from analysis of the relative merits and demerits of any of the science being discussed at the time. They focus on the people instead.
Now, a debate course is going to focus on practical action or inaction on a current event-basis rather than from a historical basis. The historical basis can tend to be a bit more distanced and shall we say..immediately distressed as someone in a debate course. We aren't be-all-and-end-all interested in costs and negatives of one political theory or action or scientific action or development...we typically want to see how the story is told, how our models of historical analysis hold up (Marx, Toynbee, Hegel, etc.).
We simply have differing concerns. I also had to speed up my description, because I have family in town. If you still find this beyond redemption, perhaps cpwill can help out. I'm quite sure he could maybe get through to you that they are completely different academic disciplines.
