The rights of women and sexual relations
Heinzen stood almost alone in the German-language press in his advocacy of women's rights. German papers occasionally noted feminist lectures of Mathilde Franziska Anneke, but aside from the Neue Zeit of St. Louis (George Schneider's short-lived paper) and Heinzen's Pionier, most German-language newspapers condemned the movement. Forty-Eighters like Reinhold Solger, Christian Esselen and Friedrich Hecker thought suffrage for women would set back culture a century. Heinzen was also an isolated voice in the German-language press which defended the legality of the Grant administration's sale of surplus arms to France during the Franco-Prussian War.
