I believe you are the one who is wrong. How could a marriage be registered in the census when it did not legally exist? Why would slaves be surveyed in the census in the first place when they were not considered people?
And for you non-sequitur, you will argue the marriage records for all to see, but not admit the truth.
Why publish the census page while not admitting that separate pages and records were kept for slaves? That is only deceptive to those that are not following very closely.
And you know very well that slave numbers as a whole as well as a percentage of the population are in the data. You also know that head of household numbers were available, which provided the marriage data.
You are just trying to affix the concept of “slaves were property, not human” to your fellow posters, and that is crude.
