Kottke points to a question posed on Reddit that has yielded some interesting answers:
So many of our grandparents were racist, and some of our parents are homophobes. Which of our own [time's] closely held beliefs will our own children and grandchildren be appalled by?
"That circumcision was once common," that some drugs are illegal while pharmaceuticals are practically pushed on us, that we smoked cigarettes, and that there was "religious overtolerance" are some of the answers posted to Reddit. I only skimmed but didn't see my number one on there: that we didn't [in most places] allow people--especially terminally ill people who feel they are being kept alive against their will and feel that they have no quality of life, but anyone, really--the right to die via assisted suicide.
Washington passed a "Death with Dignity" law this last election, and the new right to die there was recently exercised for the first time. Patient Linda Fleming, who had pancreatic cancer, said "The pain became unbearable, and it was only going to get worse. I am a very spiritual person, and it was very important to me to be conscious, clear-minded and alert at the time of my death." I am happy for her that she was able to choose to be so.
