Dutch is not a language. The people who "speak" it are Germans who suffered severe head injuries. The place we call "the Netherlands" is a German hospital colony where those unfortunate people can live while they recover. That's why it's flat and everyone walks or rides bicycles; their head injuries make them unfit to drive cars or to manage difficult terrain.
I am Belgian and live close to the border, I know plenty of them.
Whatever they are they are not german.
They have a soul, sometimes smile and have humor.
And definite proof is that when one comes into the same room as you the temperature doesn't drop significantly, also there is no detectable smell of sulfer.
Definitely not german.
