The leftists and their egos.
I couldn't do that at the uni I went to. The lecturer would mark a big "plagarism" mark even though he/she privately likes that LOL.
To be honest, I did know some who wrote conservative arguments in assignments that got really good marks in return, but they were the minority. Most who got high marks would just parrot what the general direction of the course was even though we all agreed the ideology was bunk behind the lecturers' backs. I was in engineering so perhaps this reflects our South Park-like attitudes towards kneejerk leftism?
