I would stay away from anything that could get you into a philosipoical or political p1ssing contest with your professor/instructor, I would concentrate on the cut and dry things such as the history or evoloution of the bow, Form and Science of Shooting.

Stay away from those topics that are open to ones opinion or viewpoint or something that could put you on the other side of the fence from your professor (not always but often bleeding heart liberals).

While I am certainly not saying that you should have to hide the fact that you are an avid bowhunter, but in the pure interest of grades, why push the issue.
