Just so we're clear here - and I think it's important to be - I don't have a problem with a Linux administrator who decides he wants to run his own Linux systems in a GUIless fashion. In certain circumstances (embedded, high-density-every-MB-of-RAM-matters, ultra-high security requirements) I can understand why it might be necessary or desirable.
But I do take issue with those administrators who feel it is necessary to lash out against others who choose to maintain a different set of tools on their servers. I especially have issues with those – like yourself – who can offer nothing excepting rhetoric to back up your decision.
Your arguments are consistently based on unproven assumptions about human learning patterns that simply don’t hold up to empirical testing. You even trot out appeal to authority without defining that authority in anything but the vaguest of terms. “More experience than me” is one you use…except there are plenty of Linux administrators in senior positions with decades more experience than me who agree with my take on this.
You bust out the “no true Scotsman” fallacy by implying that anyone who doesn’t agree with you isn’t a “real” systems administrator and – by virtue of disagree with you – obviously doesn’t know what they are talking about. That borders carefully on merging no true Scotsman with argument from personal incredulity.
Other sysadmins can do whatever they want. If however they want to belittle the rest of us for choosing not to limit our options, I believe it is incumbent upon them to do a damned through job of explaining their position, and backing it up with primary sources.
The whole debate has certainly devolved into ad homenim on both sides. Separate from my professional disagreements – and they certainly appear to be pretty fundamental – I believe your approach to this has been pretty damned douchey. You repeatedly assert yourself as superior in knowledge, character and professional capability without offering anything to back it up.
You attack me and my credibility based on assumptions and your own personal predjudices. I think that’s pretty damned douchy. Instead of attempting to have a rational debate about the topic you have made assertions grounded in obvious logical fallacies followed by personal and professional ad homs.
So if I obtain the impression that you, personally, may be unwell please understand that this analysis is entirely separate from the professional disagreement occurring regarding the use (or not) of GUI administration tools in various circumstances.
I am perfectly willing, capable of (and in fact, rather enjoy) having the CLI/GUI/Both debate in a dispassionate, professional setting backed by plenty of evidence, experimentation and so forth. That said, when I believe that you personally are a giant dong, don’t be surprised if I troll you.
After all, I have to do something amusing while yum runs 1064 package updates...
