The Irish do not welcome converts.

The Catholic Answers

They do. You are outside the Church. I am within it. I am of purely English origin, and was instructed and received into the Church by an Irish Priest, and found myself more than welcome among the children of the Catholic Church. Nor was I expected to become a militant Irish sympathizer from any national point of view. I retain my own national ideals. But the glory of the Catholic Church is that she unites people in one Catholic ideal, yet does not interfere with national ideals. The 400 million Catholics love very many different lands from a national point of view, but all love the one Catholic Church of Christ, that only true Catholic Church whose every member is in communion with the Bishop of Rome, successor to St. Peter himself.
