Something that I learn was , that you should always be more responsible about what you do online and how you do it , watch what you say , and don't do or feed into something about someone else that you wouldn't want done to you
 
I Believe he was saying like talking correct has became wrong . For example , people are so use to talking slang that they think talking the right way is nerdy . Also , he thinks by more then one stepping up and noticing more people will start to talk correct again because now that would be the cool thing again . For example , if everyone started talking slang because they thought it was cool , then imagine if more people talk correct , more people will think that is the new / cool thing to do and say .
