"OK. Do we need to explore again who are these people that are guaranteed a right to life liberty and the pursuit of happiness? We did it before by correcting the slavery horror so do we start with that as a model?"
Nope, we just need to see what things are, for what they are and not what we want them to be, to include what others want us to see it as. :-) What separates us from animals is the ability to reason, we all need to exercise this ability and strengthen it. If we do not, we end up with abortion, slavery, Terri, etc..... Bottom line is we lose the ability to reason the value of life. Unfortunately in our society the trend towards devaluing life is self evident.
I have hope. Our young people appear to be taking a much firmer grasp of moral issues, especially those of life, than the baby boomers did.
