Manson's song writing abilities were actually quite respected by many musicians in the sixties, before the murders. The problem is, he was, and is, a lunatic, far removed from reality.
In the music industry the truth is that personality and interpersonal skills count far more than musical talent. Manson, as spoken of by the few celebrities who admit to having known him, was clearly off balance long before the murders. People could sense there was something not quite right with him. That, in essence, is why he never got a record deal. That, in fact, is why he reacted the way he did to being rejected by the industry.
The bottom line is, he's a sick and twisted individual gone way beyond repair.

As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
