I never said people choose disabilities. I tried to point out there are other life changing issues that can affect a person that they also did not choose.
As for starting a family, I agree not all can. My mistake was jumping from their assertion that I must be young to mean I did not have the responsibilities of an older worker such as taking care of a family. The less generous interpretation of that accusation is what? I am stupid? Ignorant of life? Not suffering from the impact of issues that I did not choose?
Many also don't have the choice to start a family, no matter how badly they want it.
