My first thought was Irland. But you know.... you need to just look around for a community in your homeland and you will find a wonderful Catholic Church for you to attend and become part of it. It all has to do with a community of people who are mostly Catholics.
I live in a mostly Middle-Eastern community where the people are mostly Muslims.
But yet.... there is a strong Phillipino Catholic community. I attend my church which is mostly Phillipino members and I truly enjoy attending my church. There is also a Catholic school.
I also have another choice of attending a Catholic Church that is mostly Latinos in my community.
I think that every country is surrounded by different religions. We are not able to isolate ourselves from other religions but we are able to peacefully attend a Catholic church with lots of Catholic members.
Haiti Island is 99% Catholic. But then they have the one percent Voodoo priests who create a lot of problems for the Catholics.
Brazil is sooo poor that you always have to live in fear of being robbed unless you are super rich and have security protection.
Mexico has lots of Catholics but is surrounded by evil drug lords who have been killing a lot of their people and tourists.
I heard that England is moving towards wanting to return to the Catholic church and is changing for the better by more people becoming Catholics.
Please don't take my comments seriously because I am just thinking on top of my head and don't really have the statistics.
