"Government gave you..."
Wrong. No government gave us any of the rights that are spelled out in the Bill of Rights; those rights are given to us by God.
"In regard to specific states having buy back programs, etc., I figured any true Republicans/Libertarians would always be in favor of states rights."
Not if/when they violate the Constitution. See the 10th Amendment for clarification. Of course, if the buy-back program is non-compulsory and people want to freely give up their arms, that is up to them.
All the other little semantic dances involving the issue of confiscation are merely that. Feinstein has been been saying, in public, since 1995 that she wanted to take all guns away. She admitted she just can't get enough votes to do it. So, her menu has "Infringement" on it instead. The 1994 BAN may have not taken weapons away from anyone but by it's very nature, it banned any citizens from getting ones manufactured after the date the ban was enacted.
Sure, they are not blatantly trying to take guns away, at least not yet (I bet the citizens of New Orleans are resting easy with that soundbite though). Instead, infringement upon the ability to get types that allow citizens a reasonable chance to defend themselves from tyranny is the order of the day. Infringement by making it harder to get various types? Absolutely. Infringement by making it harder for certain people to get any? You betcha. Infringement by banning weapons that look a certain way? Of course. Infringement on accessories? Yup, yup, yup!
Here is my problem and please pardon me if I over-simplify:
"...the right of the people to keep and bear Arms, shall not be infringed."
