You are of course entitled to your opinion, and your feelings are valid.
For me, I don't really believe Elton John thinks it's alright to fight on a Saturday night, or that The Proclaimers really would walk 1,000 miles, or that Sting really thought every little thing she did was magic.
I think it's possible for a lyricist/author/screenwriter to write a story about characters, without necessarily sharing the opinions of those characters.
I don't think it's necessary to agree with the sentiment of a song to perform it. Musical theatre is on my side here 🙂
