Racism - judging people by the colour of their skin - has been on life support for a long time [1] in most liberal republics/democracies but nefarious actors are attempting to revive it in the name of identity politics. It is this type of race which can be detected using X-rays. The same group tends to support the doctrine of cultural relativism [2]. Claiming all cultures are equally valid they call criticism of behaviour related to specific cultural traits "racism", mangling the definition of that term in the process. Cultures, by definition, are social constructs.

Cultural relativism is not the norm and should not become such since there are differences between cultural traits where it is possible to state that some are objectively better than others. As an example, the cultural trait of genital mutilation is objectively worse than that of leaving girls' bits alone - and I'm open to stating the same about boys even though that would raise up a storm of protest. The cultural trait of parents marrying off their offspring without said offspring having a say in the matter is objectively worse than than that of having the offspring decide for themselves who they want to share their life with. The cultural trait of having people who achieved success within the bounds of the law - whether those be inventors, writers, athletes, successful farmers, builders or architects or anything else - is objectively better than that of having successful criminals and hoodlums as role models - yes, "street culture" with gang bangers as role models is objectively worse than whatever name can be given to cultures which have/had those inventors (etc) as role models.

X-rays can not be used to detect whether you might mutilate your newborn's genitals, marry off your 5yo daughter to your 20yo nephew or leave your children to be raised by the local street gang leaders since these traits do not depend on the colour of your skin even though there is often a correlation; correlation does not imply causation [3]. Take for example Michael Skråmo [4], a Swedish-Norwegian man who very much looked the part of such but ended up as a recruiter for islamic state in the Nordic countries. Contrast him to e.g. Luai Ahmed, a Yemeni refugee who lives in Sweden and is a vocal critic of everything Skråmo stood for. It was not Skråmo's white skin and blonde hair which made him ready to pick up a Kalashnikov, it is not Ahmed's brown skin and black hair which made him averse to the negative cultural traits related to islam.

MLK was right when he longed for a society where people would be judged on the content of their character and we were well on our way of achieving that goal. Unfortunately there are those who derive their identity - and income - from their purported position as fighters against racism (without scare quotes), a fight which was nearing its conclusion. While most old soldiers fade away [5] some have taken it upon themselves to revive their old enemy so as to keep their purpose - and income - alive. Their culture is not mine and I consider it to be objectively worse than, e.g. MLK's. If you then consider that MLK was a "black" man while I am of north-west European descent and as such have "white" skin the truth becomes clear, it is not the colour of our skin which makes us alike - it is the content of our character.

Race is not a social construct. Culture is. Nature is not a social constrict, Nurture is.
