I wasn't implying anything negative about people who like Debian. I just meant that it seemed to require more in-depth linux knowledge so it tended to be popular with the more hard-core linux fans. These people are usually anti-gui because gui's are more of an abstraction and hide a lot of the OS from people, while command line lets you do exactly what you want if you know how to do it.
I took no offense, but you seem to think that graphical and command line interfaces are mutually exclusive, which is far from true. Sure there's less in the way of hand-holding wizards (which I find extremely annoying on Windows because they always get in the way) but that doesn't mean we don't like graphical interfaces to things, it's just that some things are easier handled from the command line.
Redhat on the other hand has all the power and functionality, but provides more ease of use for those who are not experts.
Not entirely true, some of the functionality just isn't there unless you install extra software after the initial installation. And a lot of things in RedHat just aren't as consistent as they are in Debian, Debian has much stricter guidelines for things like maintaing packages and I think it helps make the distribution better over all. For instance docs are always in /usr/share/doc/package, config files are always in /etc/package, everything uses normal SysV-init scripts even display managers, installing an app will make a menu entry on every window manager installed on the system (I believe Mandrake took this system from Debian, but not sure about RedHat).
Basically there's a lower barrier to entry with RedHat or Mandrake, but overall they're a pain to maintain for long periods of time and once you get used to a nice consistent system like Debian they're even pain to install. I've had the same Debian installation for ~4 years, all I have to do to keep it currrent is 'apt-get update && apt-get upgrade' and it downloads and installs all the packages I have installed that have newer versions released. It takes a little more work/knowledge to get Debian running but I think it's more than worth it and their documentation is pretty good.
