Hi Greg27!
I appreciate your following points:
First

erhaps it is true that Christianity and the CC in particular no longer persecutes those it regards as enemies, but I am inclined to believe this is because in most Christian countries
the secular state has divorced itself from the Church, and religion has been kept free of politics, save through the democratic process. I think it is certainly a great achievement of the West that religious violence and persecution was overcome by wise Christians and also wise Western thinkers realising the best solution was to make politics and religion independent of each other, rather than trying to force divine law on all, including non-believers.
A major problem in Islam is that fundamentalists have tried to take over political power (and have in fact done so in several countries) and try to force everyone, believer or not, to adhere to divine law. I also agree at the moment Islam seems to be the world religion most prone to formenting violence and acting it out. However, I still think as a whole in terms of history, claim and counter-claim of brutality and atrocity tends to cancel each other out as the balance sheets, over the course of history, can’t be said to weigh for one religion or another in so far as the monotheistic religions are concerned. Judaism, Christianity and Islam all contain episodes of violence and undercurrents of violence done or praised in the name of faith through history, and in all religions, sacred scripture has been used to justify violence.
Third:In terms of modern-day Christianity, one needs only to look at the violent fantasies of fundamentalist Christians about how the world is going to end in a gigantic holocaust as described in the book of Revelation, and how the West (led by the U.S.) is going to be God’s instrument in that end. If people like these managed to seize power and implement a theocracy in the US or another Western country, I wonder if they would behave any differently from Saudi Arabia or Iran.
You are absolutely right, a fine post indeed.
Thanks
