I think this video is just highlighting on how uneducated our society is. People assume that you mean gay when you say hetero-sexual this way because almost no one will refer to their sexuality this way.
Being uneducated isn't the fucking problem.
I think it is. Back when Jay Leno was on, he had a "section" of his show called "jaywalking" asking people very basic questions and the vast majority of them got it wrong.
That's called being uninformed and ignorant, not uneducated.
Those are all synonymous here in the West of the West.

If someone were informing you, you could say they are educating you, relieving you of ignorance, even if not in any kind of formal setting or as part of any grand curriculum.
