as a kid I never heard a single threat uttered about damnation, though my Catholic friends sure did.
As someone who went through Catholic school, and later taught religion to Catholic students, I seriously doubt this. As I mentioned earlier, in my entire life, in any number of parishes throughout the US, I have only heard three homilies on hell.
In Catholic school, our lesson on hell was as follows: A person was given a vision of hell. Everyone was sitting around a large table and there was a feast spread out in the middle of the table. Everyone had a long spoon to reach the food, but everyone was miserable because although the spoon could reach the food, it was too long to bring what was on the spoon in reach of the mouth.
The person was then shown a vision of heaven. To his astonishment it was the same setting, with people sitting around a large table, food in the middle, and a long spoon to reach the food. Everyone was laughing, talking, and having a good time because...they were feeding each other.
We were told that God does not send people to hell. People choose to go there.
