I can speak Spanish, and the term "progresista" (progressive) was one widely used by Che Guevara in his speeches, he really used it as a synonym for socialism. And we are talking about a person who was not in favor of homosexuality, in fact, he criticized it openly, and who was also quite racist, making harsh criticisms against the Mexicans and the Latin American Indians in the famous motorcycle diary.
Nor could we say that they are liberal, rather they are libertines, but they are in favor of blatant state intervention and large reductions in liberties for individuals.
So for me the terms "liberal" and "progressive" are only a facade for "socialist", but I would not even give them this denomination, because many of those people do not even know what socialism is. It is only cultural marxism, they are socialists by idiosyncrasy and not by ideology.
That is pretty accurate for how it actually works out here in the U.S. It also should explain why our media is so anti-Trump and why they focus on everything he does "Even how he drinks water" as they've begun to lose control.
There are a few exceptions but when it comes to the media they are very outrun in the U.S. Also California is largely run by such people. Considering that is where so much of the film industry and such comes from, and where Silicon Valley began it should be no surprise they have the loudest and most numerous of voices in the media.
People are beginning to see through it though.
