It's not about Us or Them at all as I see all of us as being "of this land" regardless of our race or culture. The whole Jan 26 issue is divisive and I think that is kind of the point as your meme alludes.

Having lived through Mabo and Sorry and other campaigns where reconciliation has been attempted and concessions to activists have been made I know that changing the date isn't going to magically solve anything. It's just as likely to create more resentment from a different section of society and the activists will just move on to the next campaign to keep agitating. I don't see an end to it unless Australia is un-colonized. It is just not possible to "right the wrongs of history". Someone will always be aggrieved so my belief is that it's best to look forward rather than back.
