The point remains that when there was bloodshed, it was mutual. There were Catholic countries prosecuting Protestants as traitors and there were Protestant countries that prosecuted Catholics as traitors, and of course, everyone wanted to colonize and enlighten the pagans in the Americas and Africa.
The bloodshed ended when religion became to be viewed as a matter of intellectual choice, following the Enlightenment both in West Europe and America.
The power many Catholics want re-imposed is the power of the Catholic Church to control the Catholic character of people and institutions that want to be called Catholic without actually being Catholic in behavior. We would like our bishops to excommunicate pro-life politicians for example, and colleges that are considered Catholic to actually teach Catholicism. I am not aware of any Catholic that would want the Church to gain legislative power over people and institutions outside of it.
Yes we have Catholics who want to end America and regain Monarchy, who see the founding of the United States as a blight on Catholicism, that can only be removed once it is conquered by Rome.
Why do you think threads with a lot of what you thought were conservative voting, pro-life, anti-gay, good old right wing Catholics on them, get so strange when the topic turns to ending immigration?
