I'll address both of your fact free posts regarding RJ.
First, the above bolded. What's with this "we" nonsense? I began attending concerts in 1968 and began my musical journey in 1969. I've played rock. jazz, country (twice) soul and funk. I ran away from music and joined the military but to this day I'm still a musician and I get a guitar or bass in my hands every day I'm not in a hospital or otherwise incapacitated.
Whether you're interested or not, these are some of the threads I've started or participated in involving music and musical instruments:

There's more, but reasonable individuals might come to the conclusion that I might know what I'm talking about wrt music and musicians.
Here's the deal.
In this thread, you've made a series of assertions about satan worship and attempted to suggest that various personalities would have had to been involved in satanic circles to get where they were. In the particular instance of Robert Johnson, you parroted a myth that originated over 30 years after RJ's death that was at best 2nd hand hearsay. When pressed, you came up with nothing more than a list detailing your personal interpretation of RJ's lyrics.
When a professional musician or lyricist sits down to write, one of the principles involved is the commercial aspect of their material -would these lyrics grab a listener? is there something in the content that hits on a subject or situation that may have relevance for the listener? The classic example of the basic "boy meets girl" as inspiration for great pop songs is the best example I can think of.
In the 1930's, a black bluesman in the south is not going to have a frame of reference reflecting white popular music themes. The material that comes to mind is loss, sorrow, grief and anger. Man going to beat his woman? he's doing the devil's work - that doesn't mean he's a devil or sold his soul to the devil, it means he knows he's doing wrong. Listen to the music that RJ's bluesman contemporary's wrote and there's plenty of references to the devil.
Your innuendo about RJ and others is the finished product of the snakes you have in your head, not what was in Robert Johnson's mind.
