Yes, 'converts'. That's a whole different story.
Someone who is a 'huge believer' is utterly something different from someone who was born and raised Jewish, or Anglican and was raised that way.
Growing up Jewish/Catholic is mostly a matter of culture, tradition, community, it actually has less to do with faith. That's why I focused on 'attendance'.
They tend to be small-c conservative: normal jobs, kids attend school regularly, don't do drugs, eat reasonably well, vote, take out the garbage, stable family etc. etc..
'Converts' are a whole other issue because ironically people who grow up in a regular faith aren't likely to convert to much at all. Seekers, people who are emotional about stuff, people who have had major tragedies, drug problems, who had major family problems, maybe lived on the street ... those 'new beginning' people are often the most outwardly 'believing' but they represent a totally different cohort of behaviours.
The guy who was abused by his parents, lived on the street and smocked crack and then 'saw the light' and is a 'true believer' - this guy is going to bring most of his broken habits with him. This guy is not Ned Flanders.
The other issues is type of religion: Evangelicalism is kind of like a 'Church of Converts' - they are 'living in faith' type thing. The type who mostly watch 'Church on TV'. This is not the camp of people I mean. Again this is not about how someone outwardly talks about / believes in Jesus or whatever.
Old-school, traditional, mainline Churches are full of boring, very conscientious, small-c conservative people. This is my point. I'm not saying so much it's about faith per say, although that's probably related.
