Those who might allow the Progressive ideology to enter and occupy their minds tend to embrace the socialist idea, but, as stated in the article you posted: "The greatest evil of socialism is its central conceit. Socialism like racism, sexism, communism and so on is a collectivist ideology whereby people are judged worthy or not worthy to be rewarded or to be punished based not on the merits of the individuals behavior but on his membership in one or another group."
Out of such an ideology, then, comes the kind of grouping, or placing Creator-endowed fellow citizens, into "baskets," and labeling them as undesirable and/or "deplorable," although those citizens may be as "endowed" and capable as the accuser/judge.
