The lie? ALL MEN ARE CREATED EQUAL. It wasn't until 1868 when the 14th Amendment was written that "blacks" who were counted as 3/5 a person became a whole person.
The fuzzy murky undefined word?
"Endowed by their creator with certain unalienable rights. Among these are life, liberty and the pursuit of HAPPINESS.
We know the difference between life and death. Our creator endowed us with a right to life
We know the difference between liberty and incarceration/bondage. Our creator endowed us with a right to liberty
But the pursuit of HAPPINESS? That is seriously flawed. It makes pedophiles happy to rape children. It makes evildoers happy to torture and murder people. It makes the powerful very happy to lie to the people to cheat them and steal from them and otherwise abuse them.
The Declaration of Independence says the creator has endowed them with an unalienable right to pursue happiness. Without defining it.
So much for fuzzy unclear untrue.
What happiness do you pursue?
