and the other artists you mention and many other talented musical artists are signing about life, about their sincere love of an experience, and are just sharing their love of their talent and passion, singing and making music.
Like JRR Tolkien would say about his LoTR stories. Certainly you can read a lot into his stories and what they might say about the real world, but he always said he just wanted to tell a good story. No matter how you do it when it is a sincere and talented artistic expression it speaks to life and truth.
Bands like you saw on the other hand have an agenda. I don't know if they are talented musicians but it sounds like regardless of whatever talent they have they are primarily pushing an agenda other than just an sincere artistic wish to connect with others on a human level.
Maybe this is all a long winded way to put what someone else said about proselytizing.
