Hmmm. I can see the other side. Yes, the words were written at a different time. Depending on the particular word, it could be that is passed out of favor, OR, that is a term we now associate with racism. Or, sexism. Or, insert another 'ism word here.

Times change. Mostly, in some forward process towards 'better'. Usually. So, if the word was in the song, originally, and that word is now considered inappropriate, for good reason, or deemed to be unnecessarily offensive, why not change it? If is so significantly offends the listener or performer, as modified, maybe another song would be a better choice.

I probably don't fully understand the performer's opinion on protecting the originality or history of the song. But, I would like to hear more about it.

But, first, I need to perform some revision on my physique! The elliptical trainer calls. Like Arnold, "I'll be back".
