Actually, you make a very good point.
Define what “secure those Rights and morals” means?
If Rights and Morals already exist, which our founder’s acknowledged these existed without government...
“that to secure those rights ...governments are instituted amongst men.”
PS...
So, if we are missing the Godly morality we have no ability to secure our Rights.
The left has been very clever. They understood this and many on the Right still have not figured it out.
How did they remove our Rights?
They removed the One thing that gave us those Rights. God.
Government doesn’t secure God.
"We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge or gallantry would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution is designed only for a moral and religious people. It is wholly inadequate for any other."-- John Adams
Which in no way obviates the sworn duty of every officer of government, in every branch and at every level, to protect the unalienable rights to life, liberty and private property of the people.
It's not "either/or." It must be "all of the above" to work properly.
