I don't think ab/dl's should do anything in public that will bring unnecessary attention. Most people simply wouldn't understand what it's all about and would probably be shocked and/or disgusted. I see no harm in wearing diapers in public, as long as they are properly covered and don't emit odors that would be unpleasant to others. As for pacifiers and other such items, no I wouldn't recommend walking around in public with them where it's going to be noticed. To answer your other question, yes I do wear baby diapers in my underwear in public, and I sometimes suck my pacifier or thumb in the car. But that's a big difference from waddling through your local Walmart in a smelly, poopy diaper and shortalls with a pacifier in your mouth.
