Maybe I am wrong, I am willing to admit it happens now and then, LOL. But as I read over the song it reminded me of how the Bible talks about this very problem. Those of whom love the Lord, are becoming more and more the outcasts. Those that do not rise up in anger against other people, but humble themselves before the Lord, by following His ways are outcasts in today's world. It is taught so much that the mix of different religions is okay to do, that it must be done in order for everyone to get along. But those who follow the path set before them, the path that their heart and mind urges them to follow, become the outcasts that Jesus loves. I think this song that is set in the stage of the younger people, does not mean they don't like the older folks, it just means their way of looking at the world is different. We all go through these stages, these changes as we grow up and grow older. It is natural and has been going on for generations. Not to worry thou for these younger people will find their place in the world, and whether they be outcasts or not, I am sure they will become the people that they were meant to be.
If my take on this is wrong, that's okay. I will humbly step to the back of the line.
