The lines between species don't exist outside of our own minds. We simply make distinctions based on what our needs might be. If it's tracing the prehistoric ancestry of humanoids, the "species" designations help us keep track of those peoples. If it's reinforcing white supremacy, drawing harsh distinctions between different humans is very useful for legitimizing oppression.
This is actually bigger than evolutionary science, as all systems of understanding are fundamentally constructed. They're all tools made by our brains to help us navigate a world of near infinite complexity. That doesn't mean they aren't useful, it just means that we must always be ready to change them. The scientific method will bring theory in line with reality eventually, as accurate understandings are generally more useful. However, there will always be unfortunate truths that people would rather ignore. Only by showing the value of a truth and providing space for it will that truth finally be accepted.
The media backs the blue and are allergic to providing sympathy to protestors. It's less active decisions by billionaires telling the media what to do, and more the media being a well trained dog. They don't need to be told to run propaganda, they do it on instinct. They continue to pilot the rotting corpse of the liberal democratic world because it's all they know how to do.
