From bostonmagazine.com:
People belonged in pairs, she felt—male and female together, marching through life as if they were streaming aboard the ark.
For this reason, she found homosexuality outlandish—not immoral, and certainly not to be criminalized, but a rude disruption in the natural order of things. Homophobia was a socially acceptable form of bigotry in midcentury America, and Julia and Paul participated without shame for many years. She often used the term pedal or pedalo—French slang for a homosexual—draping it with condescension, pity, and disapproval. “I had my hair permanented at E. Arden’s, using the same pedalo I had before (I wish all the men in OUR profession in the USA were not pedals!),” she wrote to Simca. Fashion designers were “that little bunch of Pansies,” a cooking school was “a nest of homovipers,” a Boston dinner party was “peopled by 3 fags in an expensive house…. We felt hopelessly square and left when decently possible,” and San Francisco was beautiful but full of pedals—“It appears that SF is their favorite city! I’m tired of them, talented though they are.”
The opposite of homosexual, in her terminology, was “normal” or “well muscled” or “very masculine!” Or, as she often put it, “real male men.” Lesbianism was less of an affront to her, though she felt sorry for women so sexually benumbed that they were not attracted to men. (“Can’t be much fun.”)
