I think it depends mostly on how much you expect to have to interact with these people in the future. I am assuming that this is an advanced course, so you probably aren't too far away from your degree. Once you have that, you have the advantage because reputation is extremely important in any scientific field, and based on your description of these two morons I can tell you that regardless of whatever academic merits that they may possess, no one likes to deal with an abusive narcissist.
The aggression that he attempts to display is nothing more than an incredibly obvious defense mechanism, and ironically, a very childish one at that. I say, let them hang themselves by their own nooses and just get past this semester with your dignity intact. I promise that arguing will only make this worse for you, and that is exactly what someone like this wants.
It is unfortunate, but there are so many professors that can not reconcile the failings of their own endeavors with the deficits in their own character. This leads some of them to sabotage the students that do not bow to them and allow them to continue to indulge in their delusions of grandeur. Don't let this pathetic wretch get to you.
The fulfillment of your own potential will be the ultimate insult. I can tell from the mature way that you have handled this issue thus, that you are likely the most competent student in the class and are being targeted as a result. It has happened to me as well.
Before I switched to Psychology, I was an Art major. I am not boasting when I say that I was the most well-developed student in the entire student body. I owe my ability to the time and energy I spent to achieve it.
The problem is, no one knows how hard you have worked to accomplish something at face value, so I was singled out because of the distinction between my work and the rest of the students. I did not brag on myself in any way, in fact I tried to shrink as much as possible, but that becomes futile when you have to exhibit yourself. That is when I was at the mercy of the crowd, and in one particular incident, I was ripped apart for over 30 minutes straight by a few of the students and even the teacher joined in!
A lot of what was said was very personal as well, and absolutely should not have been said, especially while I was in front of 20 other people. I was lucky enough to receive an apology after discussing the matter with the teacher and the student that instigated the whole thing, but still, this was one of the many reasons I switched majors. In your case, you may not be able to resolve things, but so what?
The reason I didn't let my experience get to me is because I received the validation that I deserved from other students and faculty, and my work spoke for itself. In the same way, let your own work do the talking for you and you will continue to excel no matter what they think.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
