Interesting perspective, BitterGrey. Thinking purely of Diaper Lovers (and leaving aside the roleplay/"being babied" factor that ABs are interested in), I think there are a couple of factors that influence diaper preferences that need to be differentiated. One relates to childhood experience, while the other is purely to do with the senses and is "of the now". And one would fit very much into your thoughts about regional differences, but the other less so.
