GNU/Linux is dumb.
rms should be more aggressive and accurate — if one says “Linux” the following word should always be “kernel”, and if one’s speaking of an entire OS, one should always say “GNU” or “GNU OS”. What other OS is named by its kernel? E.g., OS X isn’t known as I-fucked-up-the-NextStep-UI/BSD/Mach.
For that matter, what OS is known by its userland?
The whole thing is moot, as Ubuntu, Debian, Fedora, etc. are increasingly the consumer-recognizable names and map to Microsoft Windoze, OS X, etc.
