Believe it or not, the Constitution is not God.
Times change--the Constitution changes with it. It's why we have the amendments. No one in 1787 could have seen the United States becoming what it is now, or how far technology has come.
You know what, forget the Constitution for a second. All government exists in it's most basic form to protect life, liberty, and property. When the government has the resources to do so, does it make any sense for it to sit back and allow the single greatest threat to the lives of its citizens run rampant?
What I'm seeing is a lot of people are hating on the healthcare reform bill on principle alone, and it's clear that a lot of them are grasping at straws now (and have been for a long time). "It's socialism!" Yeah, so what? "Socialism leads to communism!" Tell that to the UK, France, and Canada. "It's going to bankrupt the US!" Actually reduces the deficit by $138 billion over a decade. "It's going to tell me what doctor to see!" Not true. "It's unconstitutional!" Prove it.
Healthcare proponets have been more than reasonable when it comes to explaining this **** to the other side, and frankly I'm getting tired of being called liberal elitist scum because I give a damn about other people.
