Angie, I was one of the vehement "no" votes. I was being flip (I'm in a goofy mood today, because I've had my nose to the grindstone for several weeks running and I haven't had much sleep). I hope I didn't offend anyone, but you ask an excellent question and I'd like to weigh in.
So, my aversion to puff sleeves has no rational basis that I can explain. I just really don't like the look of a real puff sleeve on a jacket -- pleated or not -- on anyone. I do recognize that on some figures, it's figure-balancing. I just do. not. like. it. It's the exact same reason that I dislike magenta. It's simply too magenta. It's like trying to explain why I don't like the flavour of liver. How do you explain why you don't like liver? Well, because it tastes too much like, uh, liver.
So I'm not going to dig myself deeper by trying to take it back, but maybe I can soften what I said. Because I have no good reason for disliking puff sleeves, or magenta, or liver, I have no reason to think that people who DO like those things are somehow "wrong". I would never suggest to anyone that their preference is wrong. It's a preference. How can it be wrong?
I hope, by writing this, that it's clear that my preferences and aversions are just that: my own.
ETA: for the record, sometimes I am swayed by others, and sometimes I'm not. It depends how fervently I like something in the first place. No one's ever gonna change my opinion about, say, my black Libby Smith calf boots with red buttons -- those are RAD and always will be -- but I have been swayed before, in both directions. I initially didn't like skinny jeans, and was brought over to the dark side after a season or two. And in the other direction, my husband's disparaging comments regarding my blingy wedge sandals definitely diminished my enthusiasm for them!
