Replying to Getting Fired

I got fired today. I was a teaching assistant at my university. The man I worked for was one of the biggest asses ever. His name is Osama and he's from Jordan. He thinks that everything should be how it was when he was at the university there. He talks down to me because I am a girl. He told me that I am not a team player because I am the only one of 3 TA's brave enough to tell him that he's not treating us or the students fairly. He sends such convoluted messages like, 'you're good with the students, you grade fairly, you do your grading in a timely manner, but you're not a team player.' I think that he just has issues with me because I'm a girl and I'm willing to stand up for what I think is right.
