The proper way to do this is with an amendment.

You first. Amend away the word "posterity" in the statement of purpose.

pos·ter·i·ty/päˈsteritē/
Noun:

All future generations.

Synonyms:
progeny - issue - offspring

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

[tacticalogic]

Now there's an idea.

Demand that the Declaration of Independence be amended.

That'll make it all work.
