It's definitely a myth, and a very dangerous and self-fulfilling one. I would strongly appreciate a GUI option for many common command-line tools. I like the command-line, and do most of my work there. But sometimes GUI tools are nice to have. The problem is that most GUI tools on Linux really suck, and most Linux tools don't even have a GUI at all[1]. Contrary to popular belief, it's not due to the inadequacy of GUI toolkits on Linux, but simply due to a lack of time actually spent developing these tools.
This ends up being self-fulfilling, because it raises the barrier to getting started on Linux, which keeps out people who would be otherwise very comfortable on Linux as an OS, but simply dislike being forced to use the command-line exclusively.

[1] I'm not counting ncurses-based interfaces as GUIs for these purposes.
