If we allow this hoover dam t-shirt to be legal, we are saying to our children that it's ok to dam. Our children are our future. Do we really want them to grow up in a world full of dams? Where T-shirts are allowed to say ANYTHING, and no one has the power to stop them?
Some people will try to tell you that dams are a good thing. That some people need natural water to live. Well I say NOT IN MY BACK YARD! There are plenty of other choices for those people. We can syntheticly create water in the laboratory, without all of the side effects of natural water. If a person doesn't like that choice, the FDA says they can drink wine, or beer, or even grain alcohol. I say ZERO TOLERANCE FOR DAMS! ZERO TOLERANCE FOR T-SHIRTS! "For the children's sake".
