If you bother to review history, you will recognize that the U.S. was founded by a violent confrontation with the government.  If the British had confiscated all firearms prior to this event, it would not have occurred.  Likewise, other nations that have deprived their citizens of rights and "cleansed" their nations of the non-believers insured that there would not be a an insurrection by controlling the private ownership of firearms.
Unless our "enlightened" politicians do not have any aims at staying in control (why bother with elections) and being the dominant factor in each and everything (take over of health care and banking is just the start), I see no reason for relinquishing any of our rights, which we were born with, and have not willingly given away for perceived security and safety.  Ask anyone that has migrated from a communist country to America why they left.  Pretty sure it wasn't because it was a great place to be.
