Dealing

How does one deal with difficult people? I don't normally have too much trouble short of the odd co-worker; however, I've been struggling all semester with my professor. I like to think that I can "win" someone over with my personality and demeanor but this professor has been a tough nut. My professor has disagreed with me on every statement that comes out of my mouth, this professor denounces my type of historical work as "tainted" and that I can not be objective and truthful when it comes to history because of my employer's influence.

There have been several occasions where upon my professor has spouted rumors and myths as fact. How can I safely object to these without jeopardizing my final grade? I've thought of zinging this person on their final evaluation, but that seems petty. So, I'm putting together a professional response with all factors and documentation that I will send to this person after the semester has ended.

I realize its the goal of instructors to challenge their students, but is it their right to question a students integrity, sincerity and honesty without provocation--solely based upon their employer?
