One cannot ban religion in America. It was founded by people afraid of those like you who might try.
All you need is to appoint the right stooges for SCOTUS so they can "interpret" the Constitution the way they want.
Since even the men who wrote it weren't sure exactly what it meant, interpenetration is therefore required. Without that we would have had to burn the thing ages ago.
No, they knew what it meant.
Take for example President Madison who was called the father of the US Constitution.
Most Dims use the General Welfare clause to justify the nanny state, however, look at what Madison said about it.
"If Congress can employ money indefinitely to the general welfare,
and are the sole and supreme judges of the general welfare,
they may take the care of religion into their own hands;
they may appoint teachers in every State, county and parish
and pay them out of their public treasury;
they may take into their own hands the education of children,
establishing in like manner schools throughout the Union;
they may assume the provision of the poor;
they may undertake the regulation of all roads other than post-roads;
in short, every thing, from the highest object of state legislation
down to the most minute object of police,
would be thrown under the power of Congress.... Were the power
of Congress to be established in the latitude contended for,
it would subvert the very foundations, and transmute the very nature
of the limited Government established by the people of America."
No one gives a damn, do they.
