Let's all keep in the back of our minds that it is just about 10 years ago that a science paper appeared in which an idea was raised about a scientific theory of free will. There still isn't any science paper to point to which establishes it is real as a demonstrated fact. So all these science fans do not comprehend freedom, so they also don't understand the relationship between morality and freedom.
Why don't you all just realize your ignorance about the subject, and revert to the tried and tested ways, as explained in posts before. For many years scientists have been saying as a principle matter they can't answer "why" questions, only "how". That rule should just continue, and the offenders be confronted as pseudoscientists.
