I agree with you in many respects. But we have a fundamental challenge, which is at its root metaphysical, ethical, and epistemological: what is “good” and how do we know that something is good. You are presuming that there is some concurrence regarding those questions, such that there might be general agreement as to what is poisonous and what is salutary.
I don’t believe that such general agreement exists, because neither the standards of determination nor the nature of relevant data to make value judgments are generally shared by our population. The absence of common values makes reaching consensus over right and wrong, good and evil, no longer practicable or possible.
I think we have reached a point where a national divorce is both beneficial and necessary. The only means of demonstrating who is right and who is wrong, at least in terms of human society as a whole, is to run these diametrically opposed world views side by side
