You are correct, it is a nice song. But, you say, it is not a national anthem and it is important to note that the wrong people are pushing it for the wrong reasons.
It is very much like the open borders for anyone on the globe and encouraging, facilitating and subsidizing their arrival - all for 'humanitarian purposes'. Much of that is done through religious organizations. In fact, it is clearly a political means of "remaking" our country.
See my tagline and google the sheriff for a better understanding.
“as you say”
It’s not an “open borders” song. It’s a song by and for people who have been here for four centuries. Leave it the heck alone.
