I'm not conding his views so don't shoot me for saying this but remember the era in which Henry Ford lived. His views were not all that uncommon nor as socially distasteful as they are today. I recall reading that Henry Ford was close friends with Thomas Edison and Harvey Firestone. The three would often spend time at each others homes and as the story goes they all shared similar views.
Interesting photo below. This is left to right: President Herbert Hoover, Henry Ford, Thomas Edison, and Harvey Firestone at Edison's 82nd birthday. Ft. Myers, Florida, February 11, 1929.
Harve the ol kidder looks like he's giving the big goose-a-mundo to the young Tommy Edison.
