It wasn't really a trade union. It's purpose was to stop the re-emergence of something like the Nazis and to prevent wars. I don't think it's instincts were ever really democratic.
It must be that the Gypsy element is to be added to our political
agitation, so that hereafter the Negro alone shall not claim our entire
attention.
As I said, the 14th Amendment Clause 1 was primarily centered around whether enslaved people and their children were citizens and it seems the question of whether literally anyone born here was not taken very seriously. This question actually came up in a later case a few decades later and the court affirmed it. But I don't think there is any evidence the people who wrote this ever expected large numbers of "anchor babies". They literally dismissed that scenario as a way to prevent formerly enslaved people from being citizens.
