Dr Jacques COULARDEAU, I’m curious. You say rights, once given, can’t be taken away? That’s not at all true. Many early slaves were given freedom by their owners (at death, or via contract) only to be re-enslaved later by others (legally I might add). Also, what about Proposition 8, in this very country? It was legal to marry for 8 months, then illegal for 6 years. What about prohibition? It was legal to make and drink alcohol, then it wasn’t, then it was again.
Sorry, but US history is FILLED with examples where rights have come and gone, several times. To say this won’t happen is frankly a falsehood.
