To remove morality you have to remove humans. No humans, no politics and no science.
You can't argue with that. You either have morals and science, or you have pure objective amoral reality but no humans.
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.
