Objective truth is an oxymoron, to have objectivity you have to remove the subject. Thus eliminating the dichotomy entirely and making the argument collapse. To have true-false value arguments and statements, you need subjectivity and a frame of reference. This is a logical constraint, without anyone to observe and judge the truth, there’s no objective reality to be judged. Minerals and crystals, despite our best efforts, do not elaborate moral judgements, and they definitely don’t conduct science.
So when the tree falls in the forest and no one is around not only does it not make a sound, but the forest and the tree don't exist at all in the absence of a subjective observer?
Reality exists and continues to exist regardless of analysis or even consideration by any human. Science is a methodology invented by humans for trying to understand said reality. The earliest examples of scientific thinking are ancient and the social and moral frameworks they operated within are not at all similar to or very compatible at all with that of western Europe and North America in the early 21st century, yet underlying reality continues unabated. And yet we can continue to build off of their discoveries, despite them operating under moral and political frameworks that are abhorrent by modern standards.
You are confusing the map with the territory - the territory cares not that the mapmaker decided parts of it were immoral to include on the map the territory is what is, regardless of anyone's perspective on it. Reality does not conform to the Overton window, only what we can say without running afoul of social, political or moral issues does.
