No you don't, that's not in the Constitution

You are mistaken.
No, idiot. It's not in the Constitution that we have to investigate their influences. And not everyone agrees that is how the Constitution should be interpretedPlease tell me how we are to determine the intention of the laws established by the founders without investigating their influences. I really would like to know. Also please tell me what the purpose of a law is if you "interpret" it into being whatever you want it to mean, regardless of what it was actually supposed to mean.
