David, regardless of what you intended when you wrote the post, it's pretty clear that based on what you did write, multiple people have formed the opinion that one of their riders is at fault and that they then left you to die on the side of the road. Based on the actual info, the former isn't able to be determined, and the latter has been shown to be false.

So while I wish you the best in your long road to recovery, his response seems perfectly fair to me. He isn't trying to harass you, he is just trying to get you to clarify what you posted to clam down some of this madness.
