Does achieving a degree means that you have become a civilized and educated human being? I don't think so. Getting knowledge won't make you an educated person. The most common example of illiteracy by educated people is when there is littering iin educational institutes and illiterate people are hired to clean the mess. cramming your course books won't bring wisdom, it will only bring knowledge without enlightenment.
no offense but as you graduated in college your an educated person doesn't mean that your not an illiterate; illiteracy not comes from knowledge and wisdom only it comes from even educated person bullying and bullying others even in social media.
