These are the purposes of the CONSTITUTION, not the government. The Constitution was established to PROTECT our freedoms from government, foreign and domestic. The government is not you friend - never has been never will be. The Constitution created a government that was carefully limited. Our founders knew all to well that government is like a fox guarding the hen house, so the Constitution put a strong and short chain on the fox.
After 250 years, the chain has been rendered almost useless and the fox is now in the hen house wreaking havoc.
This government is empowered only by We the People via the Constitution, so I don’t know what you mean. The document’s stated purposes are the legitimate purposes of this government.
And the sodomite agenda is destructive of every single clause of that statement of purpose.
