It looks like the FUD factor has infiltrated the Linux community - not only does it have to be on guard against proprietary software developers who blatantly fork for code in broad daylight, it has to watch its back against its own too. I have handled most every major Linux distribution available, including S.u.S.E which I think is a very good distro. Attacking Red Hat Linux simply for S.u. Linux is but a means to an end, not an end in itself. We use the tools that we can to further our cause.
Purism is one of the chief agents of stagnation.
To say that we must use Linux and Open Source software exclusively because we advocate them is like saying that feminists must know no men, ever. Even some of the most respected members of the Linux and Open Source communities I know enjoy playing Diablo, StarCraft, and Counter Strike or creating publications, digital art, and 3D animation on the Windows and MAC platforms. In the end, this is not about Red Hat versus S.u. S.E, effective security versus severe purism, enlightenment versus hasty generalization, Bluepoint versus Mr. S.u. S.E instructor's organization, or Engels versus Mr. S.u.
