I haven't given up any rights, 2nd Amendment or otherwise.  I still have all my rights and I still have all my firearms in  my possession, except for the ones I have legally sold because they were taking up space.

You seem confused - I haven't offered any of your rights "up for sale", not on ebay, not at the Saturday market, not on ETSY.  How would I get possession of your rights, and how would I sell them?  One of my friends is my neighbor, a Lakota Sioux who grew up on the Pine Ridge reservation.  He is a millionaire, enjoying all the rights, plus a bunch of money and possessions.  He made it through hard work, in construction, like me only moreso.  And, he grew up dirt poor on the rez.  Sounds like you can make it if you try (with a little luck and a lot of hard work).

I agree that Native Americans face an uphill battle with discrimination.

One of the worst things in life is carrying around a lot of anger.  Anger can spoil your life.
