Yes, it did . . .
"No, but like-minded individuals can...the American revolution among others comes to mind."
Like-minded individuals banding together to protect a shared ethos IS A GOVERNMENT!!
This is how it really worked:
It took government soldiers escorting children into class to end segregation.
Then we are reading very different Constitutions. The one I am familiar with gives very specific powers to three branches of government. Shall we start with Article I, Section 8?
"The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
To borrow Money on the credit of the United States;
To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;"
That is just a small portion. Should I continue? Do you really know this little about the Constitution?
So the National Guard was unable to protect the rights of the Little Rock Nine that broke segregation? Last I checked, they did.
