The A.C.L.U. tweet, which was sent out Sept. 18, changed Justice Ginsburg’s words, replacing each of her references to women with “person,” “people” or a plural pronoun in brackets. Justice Ginsburg, who died last year, is a revered figure in liberal and feminist circles and directed the A.C.L.U.’s Women’s Rights Project from its founding in 1972 until she became a federal judge in 1980.
The tweet by the A.C.L.U. occasioned mockery and some anger on social media from feminists and others.
