Are you disagreeing with Kant's claim that moral behaviour can be universalized, or are you saying that the categorical imperative question begs?
I'm saying that morality must be subjective, because a moral assertion expresses a value-judgement rather than making a factual claim. So talk of universalisation or categorical imperatives, like talk of prescriptive truths, misses the point that the is-ought barrier is insuperable.
If you can cite a moral categorical imperative, or a prescriptive truth, that is not a value-judgement, please do so. Then I'll have to re-think my whole argument.
Note I posted this re the Categorical Imperative.

There are 5 Formulation of the Categorical Imperative [CI].
The above refer to the First Formulation of Universality.
As the video explained, the justification is based on reason and is self-explanatory as long as one is a human being.
Note, do not be misled by the term 'imperative.'
The CI is not meant to be prescriptive and enforceable.
The CI is merely a guide but it is grounded on pure reason [need detail discussion to justify this].
In say, Pure Geometry, the properties and qualities of a perfect triangle MUST be such and such measurements.
But such perfect measurements cannot be prescriptive and enforced upon but merely to be used as guides [Applied Geometry] to measure triangles in practice to be as close as possible to the perfect measurements.
This Pure and Applied is the same with Pure and Applied Morality and Ethics.
Note in the empirical world there is an attempt to come up with empirical universal standards for time, distances, weights, etc.
The
kilogram or kilogramme (symbol: kg) is the base unit of mass in the International System of Units (SI), and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as "Le Grand K" or "Big K"),[2] a cylinder of platinum-iridium alloy stored by the International Bureau of Weights and Measures at Saint-Cloud, France.

In the past, the 'foot' was based on the size of one person's foot, but since then there has been improvements towards higher precision.
If we can do it for empirical things why not for non-empirical matters.
It will not be easy for absolute moral values but it is not impossible to arrive at some consensus within humanity [not now but possible in the future].
