Why does where I am from matter? I'm not from any one place in particular but if I had to choose a nationality then I would say I am more Dutch than anything else.

The issue at question is the USA's treatment of modern Indians not ancient ones. The planned rally is just an ongoing example of the disrespect shown to the original inhabitants since settlers arrived there and unfortunately it shows no sign of changing.
Americans talk about "RESPECT" I see very little respect shown by you and people who think like you.
