“If men could get pregnant, abortion would be a sacrament” is a popular statement in support of abortion. Activists Florynce Kennedy and Gloria Steinem were in a taxicab (Steinem recalls it was either in Boston or Cambridge), when the elderly female Irsh cabdriver overheard their conversation and said, “Honey, if men could get pregnant, abortion would be a sacrament.”
 
The saying has been cited in print since at least 1971 and has usually been attributed to Florynce Kennedy (1916-2000).

Steinem brightens. “You know who said that? Years ago, I was in a taxi in Boston or Cambridge. There was an old Irish woman taxi driver. Flo Kennedy, the civil rights activist, was my speaking partner at the time. We were sitting in the back talking about abortion and the taxi driver turned around and she said, ‘Honey, if men could get pregnant, abortion would be a sacrament.’ And I’ve always been so sorry that I didn’t get her name.”

The Quote Verifier:
Who Said What, Where, and When
By Ralph Keyes
New York, NY: St. Martin’s Press
2006
Pg. 62:
A 1973 Ms. magazine profile of activist lawyer Florynce Kennedy (1916-2000) by Gloria Steinem included a compendium of Kennedy’s salty observations. One was “If men could get pregnant, abortion would be a sacrament.” Since then, this feminist truism has generally been attributed to Kennedy. However, a decade after making this attribution, Steinem admitted that the quip’s real author was an Irish cabdriver, an elderly woman, who—while ferrying her and Kennedy around Boston in the early 1970s—said, “Honey, if men could get pregnant, abortion would be a sacrament.”

FLORYNCE KENNEDY
While this quotation is almost always attributed to Kennedy, a colorful and outspoken attorney in the early years of the feminist movement, she said she heard it from an elderly female cabdriver in Boston in the 1960s.
