Here is a brief introduction to hyper-Calvinism. Most FR Calvinists would fall under the third category under Dr. Johnson’s ranking scheme. Some FR Calvinists could even be classified in the second category.

The bottom line is that as fallen creatures, we all seek "religion". That is, by nature we understand our fallen state, and by nature seek to repair it by creating systems through which we acquire sufficient status - "now I feel I am a good person because I do xyz".
The problem of course is that our systems are doomed to failure - unless it is a system that embraces Christ's singular act - the act which pays our price, but only if we accept it through an act of faith - and this faith is not [even] of ourselves - it is a gift.
Is the faith a GIFT - or not? Can a heart that is dead in it's trespasses and sins COME ALIVE on it's own? Or is the hand of God required to quicken the dead heart of stone?
Those who misinterpret ("I'm one of the elect - sucks to be you!") Calvin's tulip are no different than any other "salvation-by-works-alone" sect. They are simply more lost souls seeking to gain salvation - without submitting to the Savior.
