In Imperiled Innocents: Anthony Comstock and Family Reproduction in Victorian America, Nicola Beisel links Anthony Comstock and moral reform crusades to class formation and nativist fears regarding increased immigration in Boston, New York, and Philadelphia in the Gilded Age. Working from mostly published primary and secondary sources on anti-vice campaigns against abortionists, 'free love' advocates, gambling halls, and obscenity, as well as archival sources like the Josiah Leeds papers, Beisel argues that "moral reform movements... are properly seen as struggles over class reproduction." In other words, anti-vice reformers were far less interested in the well-being of the people they tried to reform than they were in keeping vice and corruption from polluting their children and endangering their elite status. By extension, vice reform revealed fears about both declining parental authority and an increased immigrant presence.
