To answer you my old classmate, whom I can not remember:

 Would you please tell me when I actually turned my face back??? For your information, I have always been on my principles. Every single person in that university knows that I have never been religious, nationalist, and anything that is important for you.  And as you said yourself, these are just important for you!!! I have my own importances and my own values. And I will stand on my principles, even if you, or anyone else, is ashamed of me or not
How do you give the right to yourself to assume that everyone is muslim??or religious??? I am not ashamed of myself to let everyone know that I am an atheist and a marxist, and I am not nationalist in the sense you are trying to express. I was born in a city of the world which is accidentally located  where you call” your country”. I have friends and family and people I love there( The most important things that I have). I have no other special feeling toward any part of the world. You can kill yourself for values that do not exist in my opinion. But that is your choice not mine.

I think you can ask the university to inteview the students before registeration every semster!! I think they agree with you that people who do not believe in what you believe, do not have the right to study there. In fact this has been done before and after revolution, and specially after revolution 57.
No big deal for you. I am happy that I am not in that university anymore. I am happy that I do not need to accept every stupid rule to have the right to study in that university.  But I am proud of myself , and my principles, and my love to those who worth it. I am proud of myself, when even in loneliness,  when my closest friends where in the worst situation, I did not regret the way I have chosen, and I am sure they did not regret it under torture as well.

P.S: I put this answer in Y! 360, and of course your comment as well, cause you started compaining about that page.

P.S 2: It is not difficult to find you on Y!360, Mr H. Ansarian. “your country” will be proud of you! I hope you receive your big reward soon. Just ask them to start a new war, and then you can defend” your country” with killing some others. I can still remeber Prof. Farshchi telling us that our profession is to kill people; more you kill, a better aerospace engineer you are. Unfortunately, I can not be the hero, and I do not want to be the hero.
