I’d be happy to support Social Democrats, who represent a venerable political tradition that has done a lot of good. Social Democrats were viciously persecuted by Socialists and slaughtered by them in huge numbers, so it’s not like one can use these appellations interchangeably. It’s pretty much like confusing socialists and national socialists (aka Nazis.)
“Social Democrats” is easier to pronounce than “Democratic Socialists.” Yet that’s not the term that was chosen. This is not a bug but a feature. But folks are so starved for a progressive alternative that they are choosing not to notice how much the alternative they are getting stinks.
