Fundamentalist Catholics aren't exactly friendly to non-Catholics. What was it that St. Cyprian said? Something like ex ecclesia nulla salus? Then there was Pope Bonifice, that there can be no salvation unless one is subject to the Pope who sits in the chair of St. Peter? Leaves all Protestants and Orthodox Christians in the cold.
Let's not pretend Calvinist fundamentalists have a corner on Christian intolerance. There are intolerant Calvinists, intolerant Baptists, intolerant Catholics, and intolerant Plymouth Brethren. Who gives a flying leap what the narrow-minded ignorants think?
The question is much more narrow - what role did God play in predestination. Whether Calvinists have been over-excited in the past is irrelevant to that question, but only serves to distract from a close read of the exegesis of the Scriptures.
Let him alone Jude, he's upset because they lost the world franchise. Luther and Calvin opened the market to everyone without their having to pay.
