The problem being of course that to those contemporary with the ratification "people" did not mean "people" as we understand the word today, just as democracy in the days of its creation, was in no way comparable with democracy as we use the term today.
It was largely taken as read that those legally recognized as "people" were as defined by Aristotle, that being, up until the mid 20th century, defined as white or indigenous men over the age of majority (usually around thirty) who owned land or property and were judged to be mentally competent enough to maintain a regular income.

And Conservatives have been trying to find workarounds or just ignore it ever since.

It is?

Interesting date, indeed.
