Eminem will be back in the UK for a show in 2010, the first in over 5 years. However, organisers were worried that the shows would be boycotted by the powerful Outrage gay rights group, who protested at previous shows and have been very effective in obstructing shows by Jamaican artists with overtly homophobic lyrics. So an agreement has been reached with the body, in which Eminem agreed not to perform lyrics that promote hate or homophobia and Outrage will not picket the shows or his hotel.
This inevitably raises the issue of censorship and free speech. But not that many people seem to be jumping to defend the right to be offensive.
