Honestly, if I was in Terri Schiavo's position - as a vegetable - I would NOT want to be kept alive. I've even commented to a number of my friends to not let me live longer than a year or two if I ended up as a vegetable because after that there really wouldn't be any point. I wouldn't outright say Terri should die like "whitesanjuro" because that is rather immature and heartless, but I think she's beyond repair and I tend to agree with those with doctorates who say she's no longer conscious within that body.
Google is a very large company, that is very successful, and very popular. I highly doubt they would post the image for World Water Day based off of the Schiavo case. I am sure each employee of Google has their own beliefs on what should happen to Terri. I'm also pretty sure there are a number of google employees who have some say over the image that is placed on the front page of their site for millions upon millions of visitors to see each day. The chances of it being an image geared torwards Terri mockingly making it to the front page is impossibly slim because Google is not a company to mock the shortcomings of others. It was indeed World Water Day and Google is known to point out international holidays such as that with customized images on their search page, so it wasn't unexpected they would come up with an image for World Water Day.
I sure hope people would stop taking this whole case to the extremes like they are... Its turning so many people into flamers and idiots. The Schiavo family is having a hard time with this choice I am sure, especially her husband. I think it should be a matter left solely to the family and everyone else should just shut up about it and stop putting it to the front page. I'm sure her husband and anyone connected with this case would appreciate some privacy. Put yourself in their positions.
