This Reuters piece on hostility towards immigrants in Northern Ireland contains the, well, oddest paragraph I've read today:

Historically, it was economic migrants from the largely Catholic Republic of Ireland who stirred up sectarian trouble in Protestant commmunities. The south, a "Celtic Tiger" until the credit crunch kicked in, is now the euro zone's weakest link.
The Pleasures of Underachievement puts it nicely: "I was wondering where all those economic migrants from the Republic were going all those years from 1922 on. Looks like it was one long border raid."
