Disrespect to parents is equal to illiteracyMembers,
A person may be highly educated with knowledge and intelligence. But if they do not know how to respect their parents, they are nothing but equal to an illiterate person.
A person's parents could be illiterate and poor who work hard and sacrifice their life to get their wards educated and employed. They dream of their wards becoming highly educated and employed to overcome their poverty, and care for the interest of their wards.
But there are persons who ignore their parents after getting educated and employed. They disrespect them and do not care them. They ill treat their parents, use abusive words, insult them in the public, and don't care them at all.
I would call them as an educated illiterate person. What do you say?
