I don't entirely disagree with you about old vs new Trek. But I think it's important to avoid the idea that Roddenberry was "trying to achieve" some grand vision. What Roddenberry was "trying to achieve" was to make a TV show, and then he was the target of hero worship by some overzealous fans, and then he bought into the hype himself. It really weakens the argument to continue to present Roddenberry as a bold visionary when this is known to not really be true.
