The only people that care or do anything student union related are these kind of people so nothing will happen in response to it.
Nothing protests freedom better than authoritarianism.
They're banning the sale of it on campus, that doesn't mean you can't get your lazy ass to the shop and buy it there.
News just in: Student Unions full of headcases.
Twas ever thus. Every Union is full of idiots who are having their one and only - thank god - taste of politics and ballsing it right up. They never represent the students as only a tiny tiny portion of students ever vote.
What motivation do they have to 'ban' the Sun?
Isn't this quite normal for SUs? They ban all kinds of things in the interest of being 'inclusive' and 'open to everyone'. It's one of the main reasons why student politics is so embarrassing. God knows what they'd do if they actually had to make important decisions.
The democratically elected SU executive officers have the right to decide what they do and do not sell in the SU shop under their remit, just as an private enterprise has such a right. As pointed out above there is no suggestion of a ban on having The Sun on SU premises and so this can't be seen as censorship.
However, I would have expected such an action to have been mandated by either:
a) A particular officer campaigning with a manifesto pledge to do this, or:
b) Some form of consultation of the student body (e.g. a referendum or similar).
There are lots and lots of newsagents in Manchester so it really isn't a big deal.
