Why does electoral history continue to be distorted?

In a recent episode, of "Sleepy Hollow", when Lieutenant Mills is going to vote, while reminding Icabod Crane that, in colonial America, black people were not even allowed to vote, I noticed how Mr. Cranes expansion, on this subject was cut-off. He was NOT "electioneering". He was trying to provide a broader view, of history.

What the man was NOT allowed to say, on air, was that, in the days, of colonial America, ONLY property owners (land, business, slaves) were allowed to vote.

That, and parliamentary/government officials.

What Icabod was, also, not allowed to mention was the fact that white children, like black children, were, for the most part, un-educated, in those early days.

In fact, in most American communities, "public school" would not even exist, for almost 125 years AFTER Mr. Cranes death.

In the days, of colonial America, if a town wanted its children taught the basics, of education, the local population HIRED European tutors. This meant that only the children, of those, who contributed to the cost, of hiring the tutor, received instruction.

During this same time period, the rich, and powerful, of the colonial days, hired European Governeses (Now known as private tutors), to school young people.

The vast majority, of Americans, white, as well as black, were neither educated, nor allowed to vote, primarily because these people were never taught the basics, of education.

These people were farmers, and merchants, who bartered for what they wanted.
