In all fairness to 2D's I think he was trying to help out.
He is a very experienced pilot, compared to most of us. I believe he looked at Whirlys posts, where she indicated that she found the cockpit workload very high, and stressful, and simply wanted to help point he in the right direction.
No doubt he has made the same mistakes in the past at some point, and has learnt to overcome them, and simply wanted to pass on his experience.
If you read his posts again, you will note that while he has tried to provide some guidance, he has also tried to include his positive support and encouragement in his posts, to keep balance.
Perhaps his point might have been better made in a pm (he may even accept that himself?) but in any case, I believe his posts were not to give his 2 cents worth, but were actually well intended, and meant to be helpful.

ps. Thanks for the thread Whirly, I've really enjoyed reading it. It helps give me a taste for my forth coming thrip (which will probably also be solo).
