Put this one down to the complexities of life. Omar Barghouti has embarked on doctoral study at Tel Aviv university. He's a prominent campaigner for boycotting Israeli universities:
Thousands of students at the university have already signed a petition calling on the board of governors to bar Omar Barghouti from the lecture halls, but the university is upholding the cause of academic freedom.
The university is right and the signers of the petition wrong. Barghouti, for his part, sees this as 'a personal matter'. (Thanks: HG.)
