Don't let socialists get away with calling themselves "progressive." They are anything but that.
The "Progressive" movement never really was about progress. Not in the way most people in a liberal democracy would define social progress. They have a vision of a socialist, non-racist society, which they undermine at every turn by defining everything in terms of race. And despite their claims to the desire of a society without class differentiation, they believe very religiously in class. The class of the ruling and the ruled. And guess which class they aspire to?
What is progress?
Technological progress is very easily defined. While there may be negative environmental ramifications to some technologies, innovations which improve the speed and efficiency of performing tasks qualify. Why is it that capitalist societies have always been more advanced and produced more technological innovations than non-capitalist ones?
Less government interference and more incentive for individual creativity.
But that doesn't line up with a "Progressive" socialist world-view which implicitly creates disincentives for individual achievement in the form of fewer rewards for more work than a capitalist culture. So as far as technology goes, "progressives" are actually regressive.
What about social policy?
In an ideal world, all people would be treated and thought of as equal regardless of their skin color, race, or ethnicity. In our world, the people who are arguing for racial preference, who are suggesting racial conspiracies and ethnic guilt are none other than the "progressives."
Judging a person on the basis of race, whatever your motive, is racism. Racism is regressive behavior.
Which leads to cultural relativism and equivalence - the ideas that all cultures are equal.
Some cultures suppress women's rights. Some cultures persecute Gays and minorities. Some cultures do not allow press freedom and some will execute you for blasphemy.
These are all manifestations that a liberal democracy would consider backward. But cultural relativists say that those cultures are equal to ours.
Who are the cultural relativists in our society? You guessed it. The self described "progressives".
Lots of self-described "progressives" are adherents of Marxism. Yup, the same Marxism that is responsible for millions of deaths under Lenin, Stalin, Mao, and the repression of free speech and civil rights in the Soviet Union, Cuba, North Korea, and more.
So the next time one of these buffoons tries to call themselves a "progressive," consider reminding them: "No. You're not progressive. You're a follower of a regressive socialist ideology. The rest of us have already progressed beyond you."
