Guys, that line is saying who WROTE the constitution, and that's it! Nothing else!
It's exactly what me and Warrior said:
"We the People of the United States [...] do ordain and establish this Constitution[.....]"
Arguing about that line is meaningless! It's talking about the writers, not who it's for.
If you want to argue about something, argue about the line that says, "WE hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the Pursuit of Happiness"
