Do you understand that someone moving for economic, cultural or pleasure reasons is not the same as their country sending them? What responsibility do we have for them that we should take then back?
Ireland's population didn't stop shrinking after the 1840s Famine until 1963. Those that stayed turned the country from agricultural backwater to a net-contributing EU nation. We didn't have to displace anyone, strip mine a continent, or restrict immigration to whites only either to achieve that.
Ireland allowed it? That's a very interesting take. Could you expand on that please?
