No doubt about there being considerable debate over the "second chance" doctrine. My experience with those who are adamant about there being a second chance after death, they generally don't know the scriptures, and they fail miserably when it comes to rightly dividing the word of God when trying to defend their position.
Broad spectrum debates are what we're generally left with on topics that don't have a verse, or verses, that clearly spell it all out. Many people have problems with allowing systematic study through scripture to paint the panorama portraiture for them.
