Yes there is a big difference. While totally illegitimate, immoral and criminal, the Nazi’s had a grievance against the Jews. “Progressives” don’t care whose lives are snuffed, Christians, Jews, Blacks, Whites...doesn’t matter.
And millions of other human beings, apparently. At least 13 million murdered, 6 million of whom were Jewish.
That's one difference, I guess. Planned Parenthood has killed more people in the name of eugenics (and profit) than the Nazis ever did. 45 million have died from abortion since 1973 and Planned Parenthood dominates the market -- with a virtually monopolistic share.
