Some of them don't even know how amendments work. They think the 2nd amendment was passed down by God on stone tablets.
I've argued with a person that didn't know amendments could change other amendments. Nor did he know how amendments were voted on. But he swore the amendments were perfect when written and couldn't possibly be changed.
In the article at least, De Santis hasn't explained how that works for the "good" Americans he wants to keep. Is every infant just not a citizen anymore until they can pass the test?
Don't even try to think about the downstream affects of that on healthcare and education.
