I don't even know what you're trying to say right now. 'Extraordinary claims require extraordinary evidence' means that if you are making a claim that runs significantly contrary to established evidence and procedure up to this point, you need to provide convincing proof for it. Comparing that to how expensive a bill is is apples and oranges.
Not only that, but my argument is the research HAD been done, just not research specifically commissioned by Congress for the passage of that particular bill. Congress almost never does that sort of thing because studies take years to do, and won't be completed until long after the current Congress has come and gone. In this case there were MOUNTAINS of studies, so instead of wasting everyone's time, they used the available evidence. (btw, pretty much all legislation works this way)
I don't think you guys understand how legislating works.
