Three cheers for Tony Blair.

"They come here and they play by our rules and our way of life," Blair said at his monthly news conference. "If they don't, they are going to have to go."

U.K. Institutes New Deportation Measures

Foreigners who preach hatred, sponsor violence or belong to extremist groups could be deported from Britain under strict new measures that Prime Minister Tony Blair announced Friday, nearly a month after suicide bombers killed 52 people on London's transit system.

Membership in extremist Islamic groups such as Hizb-ut-Tahrir would become a crime under the new measures. The group, which advocates the creation of an Islamic state in Central Asia, already is outlawed in several countries.

Blair said the government also would compile a list of Web sites, bookshops and centers that incite hatred and violence. British nationals involved with such organizations could face strict penalties. Foreign nationals could be deported, he said.

You don't shout fire in a crowded theater, not even as a prank. You don't teach people to kill those who are hosting you in their country either - and they're always serious. There's a word for these types of people in the dictionary - parasite is too good a term - "one who habitually takes advantage of the generosity of others without making any useful return."

In the famous words of Bananarama - Na na na na, na na na na, hey hey, GOODBYE!
