Progress is just a buzz word they use to encompass what they want to do. Here is a breakdown of it:

What they falsely claim it is: To change certain necessary things for the betterment of society.

What it looks like to a normie just starting to see the truth: Change for the sake of change.

What it looks like if you look closer: Changing everything in order to usher in a demonic world order. Synonymous with communism since part of this new world order is to have all the demonic leaders hold absolute power over the people because most people will not accept it without being forced to at the muzzle of a gun.
