Sorry about your accident.
That biker was an a-hole of epic proportions. I ride motorcycles. I have ridden alongside bicyclists riding down mountain road and the last thing I want to do is have a collision with them or cause them to crash. I've had bicyclists blocking the road on a twisty road because they are not going fast enough, so I just slow down, wait for them to get to a clear straightaway where they can ride closer to the side of the road so I can pass. No matter what, even if the bicyclist is being a jerk, the responsibility is on the motorcyclist to avoid a collision because we have the advantage of power & weight. Collide with bicyclist and he/she will be the one who really gets hurt.
I hope you heal quickly.
