There is a popular sobriquet for over-the-top Linux zealots that's been around for some time now, and seems to be picking up in frequency of usage: freetard. The current best illustration of Linux freetardation comes to to us via the Linux Haters blog.
It appears that the current cause célèbre freetard, Lundumb, a.k.a. Brian Lunduke, came to the attention of the Linux Hater because Lundumb (badly) produced a video based on a presentation Lumbdumb titled, charmingly enough, "Linux Sucks!" As if far too many of us in the community don't know that already.
Well, the next thing you know ol' Linux Hater is a-hatin' on Lundumb's presentation, when Lundumb flings out an outlandish challenge: I challenge you, [good] sir (or madam), to a debate. With Live audio/video... If Linux Hater does not take me up on this? He (or she) is a total and complete coward...
Coward? You're calling Linux Hater a coward? Do you know who the real coward in the Linux community is? Her name is Pamela Jones. Yeah, that Pamela Jones, keeper of Groklaw.
