I'm suggesting not all are rude; I see many uplifting comments. A number are rude - and maybe those who are pre-oriented to replying in text on a partially anonymous board with a pedantic nature are pre-inclined to be more rude.

Engineers by design are used to problem solving or working through the problem solving. If they're not solving the problem - then they would be in "what's wrong with this approach" mode and some may see it as rude.
