For what it's worth, in my 44 years in the Northeast, I've never thought "holy rollers" was a sect-specific term. In my experience it simply referred to ANYbody who aggressively promoted their religious views. So for those who are offended by the use of the term, for many of us it is nothing more than the equivalent of "church ladies" in the Dana Carvey sense. If I'm tempted to use it in future I'll try to be more sensitive since it appears that it does have a very specific meaning to many people in a different geographical area, but conversely, other folks can rest assured that when many of us throw the term around it's on the level of an eye rolling insult, not a vicious one.
Traditionally in the Roman Catholic church, unbaptized babies didn't go to Heaven -- they went to Limbo. Thus the haste to baptize any baby that looked like it was in danger. I believe they're dropping Limbo entirely (if they haven't already) since as a Cardinal the current Pope was leading a committee that was studying the issue and had formally stated his opinion that it was never more than a hypothesis.
