No. And that but illustrates that the "metaphor" is not apt. Both the abortionists and the abolitionists attacked the right of the several States to not accept their (the abortionists and abolitionists) imposed "morality." It is of particular note that the abortion decision, overturning the traditional laws of every State, was made possible by the 14th Amendment, which was the creature of the Republican Radicals, who sprung from the Abolitionist movement. Both movements were absolutely intolerant of any dissent.
But the most significant reason for rejecting this "metaphor," is that it completely misunderstands the players, then and now. The abortion movement is a Feminist creation. Feminism sprung from the same ideological roots as the Abolitionist and Prohibitionist movements. All three were launched by the same groups in upstate New York, Massachusetts, etc., in the 1830s and 1840s. This is very evident to me, because the Western outpost of the three-headed movement was in Oberlin, Ohio, where I went to College. (I went there to better train myself to fight the "Liberals," not join them; but I can attest the historic influence of the three-headed movement up there.)
I realize that it may surprise some who are not educated as to the period, to read that Prohibition grew out of the same roots as Abolitionism and Feminism; but it is true. In fact, to recur to the Oberlin example, it should be noted that the Anti-Saloon League was founded in the Oberlin College Library in the 1890s. It was the Anti-Saloon League which pushed the 18th Amendment through immediately after World War I. (And, of course, Oberlin was founded by Abolitionists, booted out of the Lane Seminary in Cincinnati, in 1833. It was a center of Feminist activity from its start, being also the first coeducational Liberal Arts College.)
Now you have gotten me to go into some of the details I was trying to avoid. But let me suggest a better "metaphor," the murderous abolitionist John Brown and his fanatics and the screaming "right to choosers," advocating mass killing today.
