I'm sure IWAF doesn't hate blind people, but I don't think he's terribly bothered about them either. Personally, I found that piece really shocking.
I think it's best not to personalise these things. My comments have been based on whether or not I think the experiences of blind people such as those reported in the Cambridge article justify licensing cyclists to use the public highways. It is sobering to be made to think about how difficult living with blindness must be but I wasn't shocked by what I read as it lacked enough detail to be clear about the nature of the incidents mentioned.
