You can wax poetic all you want. A sense of order on the roads is important. Slow traffic stay right.
It seems that you have very little understanding of what is safe and legal at an intersection when bicycling. More than 80 percent of car bicycle collisions happen at intersections. The OP was operating his bicycle in a safe and orderly manner. The individual in the car who approached from the rear saw a bicycle and drove over the posted speed limit and stopped next to the bicyclist illegally in the oncoming lane. He then stated his desire to make a right turn. This individual wanted to punish someone for being on his road. I have seen dogs dominating other dogs at the dog park with more manners than he showed. You are not required by the law to stay right at an intersection.
