That's not what you originally said. You said there are no Catholic terrorists. That's different than Catholic priests calling for the IRA to terrorize N.I. You've moved the goal posts now.
But if you want the US government can tell you about Catholic charities funneling money to the IRA. There's also plenty of evidence that Catholic priests in Ireland actively working with the IRA, hiding them, etc.
I left the Catholic church over exactly this issue, although not in Ireland. In South and Central America and in Africa, Catholic "Missionaries," chief among them the American Maryknoll order, were teaching "Liberation Theology," which among other things said, "Jesus was the first Communist," and "Jesus was a revolutionary," and "If he were alive today he would support Fidel and Los Barbudos against the Yanqui."
The Maryknolls ran safe houses. They indoctrinated terrorists. They stored, maintained, and issued weapons.
They did all this with money from decent Catholics in America who thought they were helping hard-working missionaries to spread the word of the Lord, and who would have been mortified if they knew what their contributions really did.
So don't say there are no Catholic terrorists. My grandmother had been giving to these creeps for forty-something years, and they were leaning on her for a position in her will. I walked her through what was being done in her name in El Salvador, Nicaragua (where priests acted as informers and betrayed confessional sanctity to the Sandinista regime! Out of "solidarity!") and other places -- it was hard to do only using open sources, but fortunately all the Maryknoll stuff that had been sent to her, she still had.
After that the priest that had done my confirmation contacted me and criticized me for it (how did he learn? Her pastor, or the Maryknolls?) and told me I was "greedy" and "mean" and "a bad Catholic" because I didn't share "the missionary order's committment to 'social justice'" meaning, of course, 'revolution.'
There are many, many good, decent, Christian people in the Catholic Church at all levels from the lowliest parishioner to the highest levels of the hierarchy. I have no doubt that while the Maryknolls wanted me and my friends and our Latino allies dead, that the Pope (John Paul II) was on our side. But there are also some bad people in the church. After all, it's made up of many millions, all (by definition) sinners.
I have no opinion on Mother Teresa. Hitchens is so angry that he casts doubt on his own case, and I'm sure I'll never see the Penn and Teller show. But there are most definitely Catholic terrorists, and you can take that to the bank.
