It's so foreign to me to think that there are people who only use spinning gear. I could be completely wrong but it almost seems geographical. People in the north are more likely to use spinning gear while people in the south are more likely to use baitcasters. Here in TX, it's the opposite, most guys will have a boat full of baitcasters and maybe 1 or 2 spinning combos that only get used if all else fails.
I don't care what anyone uses, it's just interesting to me. Fishing is supposed to be fun, a person should fish with whatever makes them happy, it doesn't matter what anyone else uses or what anyone else thinks about it.
