If _____ WAS an ordinary person. Where did this municipal-school English come from? It should be: If _______ WERE an ordinary person. The subjunctive in English take the plural.
This is so disparaging a section. There are no ordinary person anymore, social media has changed all that. If you are talking about the urban-rural divide then you got the subject line completely wrong. If you are not upto date with reality and how the current generation dresses and acts, then, at least grow up!
