I had never heard it expressed in this way, but the link describes the U. S. as having a “passion for equality.” That in the U. S. we still have abortion rights, gay marriage rights and have done away legally with racial segregation is explained by this simple value.
The link author is a law professor. He tried to explain to students why someone who bakes wedding cakes is so far required to make them for gay weddings even though the baker claims it violated his religion. Law students could not understand why anyone would think the baker should have the right to refuse.
The professor tried a different hypothetical case, an orthodox Jewish person who is a florist. There was a request for flowers for a marriage of a cultural Jew to someone outside the faith. Such marriages are against the florist’s religion and, in this hypothetical case, the florist refused flowers. The students again had no sympathy with the florist’s position.
The professor concluded that this “passion for equality” is a powerful ongoing value that is hard to shake. It eventually prevailed in slavery and then in segregation. I can say from experience, distaste for gay people was deep in the psych of the general public when I published my first proclamations promoting equity. The “passion for equality” overcame both of these.
I think a passion for equal opportunity for women will eventually push anti abortion politics back into it’s proper place as individual opinions instead of public policy.
