With respect to the OP.....could you try to digest the premise, and then attempt to make an actual point.
This is where you're mistaken. The OP doesn't deserve any respect.
So....as you still have no answer.....
...is this your pathetic attempt to become relevant?
To pretend that that you actually understood the OP?
Which is it?
The point is that you can go anywhere in the world and people know the words of John Lennon and what he wanted to say to the world. His music has been loved and continues to be loved by millions since he first appeared and long after he has gone. Maybe tens of millions. Maybe hundreds of millions. Maybe as time goes by, billions. He had a tremendous impact on the world. Unlike the temporary impacts world leaders have, John Lennon will continue to have an impact on the world. That is what happens with art. It lives on after the artist dies. The artist name may live on, and his or her's work may live on, and some written works may live on, but the message of those artist can become changed and forgotten with time. Poetry and music can go on forever. The message of a song can go on forever. John Lennon put his feeling into poetry and song. His feelings will continue to influence the beliefs and opinions of countless people far into the future. Not many in world history have ever gained that claim and status. Perhaps you can or someone else can name some. That would be an interesting debate.
