So I'm essence, the arm can go from rubbing the head of a small child, to signaling a bus to stop, to a Nazi salute, to waving to a friend, to hailing a taxi.
Seems your image is more in the waving to a friend/hailing a taxi zone. You'll need to search a bit harder to find the area attributed to a Nazi salute.
All good, it's Saturday and the sun is shining. Relax.
