He remained unacceptable

Poster made in Lithuania, on the basis of the following story:

When my uncle was at the university, he was affiliated to one of the political parties, and in one of the lectures my uncle and a doctor argued on one of the subjects until he was expelled from the lecture, after that he received the news that he had not succeeded/failed in the course because of the doctor. Next year my uncle re-register in the course but the same doctor didn’t let him pass the course, my father went to try to find out the problem, as my father was loved by many doctors, and they told him that the doctor would continue to not let him succeeded , saying: “Your brother does not have a living here.”
My uncle traveled to complete his university studies abroad, and when he returned to his country to find a job; He was approved to work in an  Airport, then they told him that they had to go to the  intelligence department, and after two weeks a response from the intelligence arrived at the airport saying, “We do not advise.” So they apologised to him, and he remained unacceptable throughout his life in a position or work because of his political opinions.
