It is always those who are speaking up for th dissenting or marginalised perspective and values, that the argument for so-called 'balance' is directed.
Fo instance posters tha tI was putting up which had a sing'Stop the War', were torn down by security staff; adn it was justified on the basis that they were too 'political'. When th army, the airforce adn the navy came to the college to recruit, the management did not see that as being 'political' or requiring 'balance' with the presence of say, peace activists .
