I had this same issue and wondered why it didn't happen with a bitbucket repo that was cloned with https. Looking into it a bit I found that the config for the BB repo had a URL that included my username. So I manually edited the config for my GH repo like so and voila, no more username prompt.
I'm on Windows.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
