Am I indigenous?

I have recently set up a twitter account, not to write anything, but more to follow others, one account I’m following is the UN, I want to keep a beady eye on them! Most of their posts, or are they tweets, are the usual anaemic nonsense, but one tweet this morning struck me!

I may be wrong, but isn’t everyone indigenous to somewhere? Aren’t we all indigenous? Or do they only mean non White people?

I wonder.
