Already the reception centers are full, soon to be overflowing with Africans and Asians who do not kill their babies. Even without dismembering their babies, white Irish women are already well below replacement birth rates.
Ireland, being small, will disappear very quickly.
The fertility rate in 1970 was 3.7 (above replacement), but as of 2018 has dropped to 1.9 (higher than USA, by the way, but below replacement). The fertility rate will unquestionably plummet with the legalization of abortion.
Bottom line --- barring a demographic miracle the likes of which has never been seen in modern society --- they will never recover.
