Pedophila was perfectly normal in Alabama back then, say Alabama Seniors.
Yes, that is certainly correct, and was not limited to Alabama. Kinsey found that 24% of the women in his study had been approached by adult males when they were pre-pubescent. The women approached by Moore were not pre-pubescent. For females 13-18, the percentage approached by adult males would have to be quite high.
There is, to my knowledge, no data specific to Moore's case, i.e. the percentage of teen girls approached romantically by men aged 30 or more, but I am guessing that the number is not insignificant, and (again a guess) would be even higher in Alabama 40 years ago. I'm from the North, and met my wife in that same era (1979), when she was 19 and I was 30, and I never once thought the age gap might be inappropriate. We were together for a couple of years, then married, had a child, and although we are no longer together, are still friends and spend some holidays together with our grandchildren. So as you may imagine, I didn't really see our relationship as perverse. Pretty sure she did not either.
I am not trying to act as Moore's apologist. Our situations were different.
My wife and I met through work and I was not trolling the malls (or anyplace else) for chicks. Moreover, there is a big difference between 14 and 19, and an even bigger difference between fun dates in public with friends and colleagues, and whatever Moore was doing with that 14-year-old girl.
But I believe these people when they say that many Alabama teens in those days were approached by and/or dating older men, and everyone thought it was just the way things were.
