What have I done in regard to government injustice's to Native American Indians?

Well I donate money via their craps tables.

Assuming you are talking of historical injustices done to the Native American Indians you are generally referring to things which occurred a little bit before my time. As such there was little that I could do.

However the political party to which I contribute works toward advancing the following plank in its platform.

"The rights of American Indians have been usurped over the years. We support the following remedies: (1) individuals should be free to select their own citizenship and tribes should be free to select the level of autonomy the tribe wishes, (2) Indians should have their property rights restored, including rights of easement, access, hunting, and fishing, (3) the Bureau of Indian Affairs should be abolished leaving tribal members to determine their own system of governance, and (4) negotiations should be undertaken to resolve all outstanding differences between the tribes and the government."

What I have done is to support candidates for office who will advance this platform.
