@eckhard
Thank you so much for your message. That is exactly why I am getting confused. I know and 100% agree with your point on wanting the root to stall rather than the tip on a swept back wing.
The exact question:
Why so important to prevent stall at the root of a swept back wing?
Maybe it is sort of a trick question and you would have to argue in the case of wanting it to stall at he root rather than the tip first including all your mentioned points.
Many thanks , would love to hear your thoughts
