That's the first I've ever heard of the pedophile charge. Pimp, pervert, crook -- those I knew. But pedophile?
I guess Mean Dog is noting Alexander's well-reknowned fondness for children, as well as sexual licenstiousness and presuming the two are related. The pimp charge is probably pretty fair; he did throw a banquet featuring prostitutes. One account may be exaggerated, but Alexander was very definitely a very immoral man.
