Um, Lost One, when you came into the conversation, we were already in the *middle* of it, as SE pointed out. Since you haven't the desire to go back a few pages, look below to see what you most likely missed...
Oh, and I am personally experienced with how "subjective" grading can be, given that I taught English myself. In this case, however, my complaint is about much more besides my grade.
What is grimly amusing about this whole thing is that he never graded one single assignment. Never even read our articles until the class was over and done! What's more, the "intro" he wrote to our book was a pathetic 1 1/2 paragraphs full of vague, juvenile platitudes. We had no syllabus. Assignments were often given two or three days before our class. Classtime was frittered away with endless crits and backtracking, useless lines of questioning, inappropriate comments, and so on and so forth. First, I will go over all these things and ultimately wind up discussing my grade.
My blood is boiling right now because I found out that this twerp of a grad instructor I had this past semester had my classmates doing the teacher evaluations while he was still in the room! Not only that, but he offered them beers as they were filling them out. Talk about being ridiculously unethical! Beer wouldn't have worked on me, of course. 
HOWEVER, this guy is unbelievable.
See, he set up an "extra" class period since we hadn't been able to look at the proofs, given all the time he wasted throughout the whole semester.
