A book store in the US yielded to violent threats from supporters of Israel, by publishing a statement condemning the Palestinian Boycott, Divestment and Sanctions campaign.

Now students opposed to the occupation of Palestine have launched a nonviolent campaign calling on the bookstore to move back to a neutral stance.

I think it is wrong to accuse the bookstore of "suppression of literary freedom", but it is clear that that was the aim of those that made the threats.
