I came across with this quote today and instantly thought of coppermine forums.
Never argue with an idiot. They pull you down to their level, then beat you with experience.
There is no dearth of such morons on coppermine forums.
Recently I have seen many users criticizing support team of being rude and un-friendly. They claim that we should answer their each and every question (which we do unless the question has already been asked many times) as they are using our product. What they don’t understand is that coppermine is not a commercial product but a FREE open source application which comes with no warranty for support. Despite of this we try to help as much as possible and reply to more than 95% of threads.
Threads started by such morons lead to flames and arguments and they generally beat us with their experience.
