No one that I’ve ever met who came from a left wing ideology as a child EVER, EVER outgrew it - with the exception of David Horowitz and a handful of others. Conservatives often “outgrow” it - because they go on to college.
Yet both never gave up their childhood belief that the Republican Party was the party of the rich and privileged. Nothing I said to them ever made a dent in their belief that the Democrat Party was the party of good people who cared. Not even when the Democrats became the party of abortion on demand, homosexual marriage, and Bill Clinton did they change their belief about the saintliness of Democrats. I used to kid them they both believed FDR was still the president.
My family changed from Leftism. Reading Ayn Rand, plus the biased “New York Times’s” accounts of the so-called antiwar demonstrators changed me and my brother’s mind about so-called scientific socialism.
