That's like saying "being a vehicle is how a lot of cars work"; the reasons on why the cipher is flawed are a bit more specific than that. As for the elitist arrogance, whilst I'm sure these exist in other security-related interactions across the world, the interaction that's the subject of this thread involves plenty of polite comments that - point out author's lack of background knowledge - refer to short-cut theorems that help evaluate a cipher, implying the author should learn about these theorems - explicitly tell the author to learn about these theorems In response to this, the very first reply the author gives is "It almost sounds like you have had your soul crushed by bureaucracy over the years and have lost all passion for this field. I hope that's not true." Yeah, however much "arrogant" you interpret the security people in this thread to be, it's only fair to interpret the OP (Mark McCarron) to be 2-3x as arrogant.
