Honestly, I believe so, in that you are a little too sensitive.
The example you bring up is not at anyone's expense.
As far as blind children being less likely to be hit by cars, I believe that statement to be entirely accurate. It was an observation, and so you are only offended at my opinion in that case. Not to pick on you, but I think you are a perfect example of people whose offense I am not responsible for. But you know I love ya'.
