centuri0n has a great post about those who are against calvinism. You can read it HERE, but I had to post one of the brands here.
This is a major sore point for me. People who rant and rave about calvinism without even really knowing anything about the points
(other than God choosing to send people to hell)..
 Hunt’s Tomato Paste: “I hate Calvinism, but I can’t accurately describe the Doctrines which constitute such a thing.” Listen: read a book or something — and I mean read the whole book, don;t skim it in hopes that you have picked out the useful bits by mistake. The Five Points of Calvinism, 2nd Ed., By D.N. Steele, C.C. Thomas & S.L. Quinn, would be a great and brief place for you to start.
