I think the real reason they’re doing this is to ultimately get “God Bless America” banned. Kate Smith is one of the best known singers of the song, and her version is/was a go to for several sports teams. The hatred for such a patriotic song, esp. with “God” in the title, must be too much for certain special snowflakes!
Which is a way station to the ultimate, ban "The Star Spangled Banner", and replace it with "This Land Is Your Land", or some such.
