Or harkening back a few years:

"What is happening to our young people? They disrespect their elders, they disobey their parents. They ignore the law. They riot in the streets inflamed with wild notions. Their morals are decaying. What is to become of them?"

4th century BC (Plato)

The article is pure bunk - none of these questions are illegal. Discrimination based on on answers to these questions is illegal, but not asking them.

As an interviewer, these are questions which should never be asked, because they leave you open to an accusation of discrimination. That doesn't make them illegal.
