Values: Philosophy reduced to a slanging match - Brexit and Capital Punishment

Brexit Correlates with belief in Capital Punishment
A peculiar study concludes that belief in leaving the EU and belief in traditional values like capital punishment have a strong correlation.
The objection to this is that the referendum reduced a complex issue to ultra-simplicity. As a result exit was all too easily seen as a way to achieve ends that are not necessary to it.
But the greatest problem is relates to the nature of ethical values. Nobody is likely to call Brexit a Value. Why then capital punishment. They are both pragmatics that are not absolutely fundamental and indivisible, and must both be based on genuine values.
Making pragmatic ideas 'values' must destroy rational philosophical debate. Reducing it to a slanging match.
There is not a single elementary value that states anything specific and practical about what we or society should do. They only make sense in the way they relate and oppose each other so as to indicate choice.
There is just the one unavoidable slanging match, and that is in the elementary choice or lack of it. And even there, a multitude of pressures exerted by a vast world through a person's life may alter him willy-nilly.
Do we as individuals in society, and those societies, cooperate, compete, or stand aloof from each other.

Oddly related to the latter, is current ideas about racism. There is again a tendency to treat this as a fundamental value the meaning of which is obvious. It can only be treated as a value in relation to other values, and not banal anti-racism or racial blindness. If all the world or its people were exactly the same in every attribute, it would be a dead society and probably literally so. Differences that, in themselves, have no ethical significance are important in terms of a value of Diversity. We need to preserve Big Ender and Small Ender societies, because neither of them is right or wrong.
