But this was nothing compared with the utter destruction of society that the post office was going to bring to America. In Britain, even if you managed to mail a letter in secret, the reply would be delivered to your house and you could be found out. But women in America picked up their letters at the post office, even renting boxes there just like we can today. Obviously, this meant they were all going to become prostitutes.
Women find sorting machines unbelievably erotic.
According to one pseudonymous writer at the time, having "clandestine correspondence with unprincipled men" was already affecting "a thousand schoolgirls a week" and opening their minds to "abnormal channels." He claimed madams had started hanging out in post offices specifically to lure these ready and willing stamp-sluts into a life of prostitution.
It sounds insane, but respectable ladies turning to whores all because they had control over their correspondence was such a common concern for men that when Congress was debating implementing home delivery like they had in England, one of the arguments in its favor was that women would no longer need to go to the post office (and, presumably, that their husbands or fathers could once again see who they were getting letters from) thus stopping all that civilization-ending, postal-related sex they must be having.
