You are wrong. The Bishop's conclude that it is not acceptable to withdraw Food and Nutrition in someone in Terri's condition. Also recent statements by Pope John PaulII and Vatican clergy clarify Church teaching on this matter. Below is a statement from the USCCB website you cited.
In light of these concerns, it is our considered judgment that while legitimate Catholic moral debate continues, decisions about these patients should be guided by a presumption in favor of medically assisted nutrition and hydration. A decision to discontinue such measures should be made in light of a careful assessment of the burdens and benefits of nutrition and hydration for the individual patient and his or her family and community. Such measures must not be withdrawn in order to cause death, but they may be withdrawn if they offer no reasonable hope of sustaining life or pose excessive risks or burdens. We also believe that social and health care policies should be carefully framed so that these patients are not routinely classified as "terminal" or as prime candidates for the discontinuance of even minimal means of life support.
You so very obviously haven't read the report. There are dozens of angles that make it okay to withhold food and hydration and Terri fits into a couple of them.
