I think it was someone over on imgur who pointed out that this images makes the opposite point that the original poster wanted to convey. The Native Americans DID let the immigrants in, and they were massacred by the millions.
@jonson Really? Is there someone daft enough to take this any way other then that Native Americans let (sort of) Europeans settle and got handed a hot plate of genocide? P.S. I am *not* digging around on Imgur for context.
@LordJohnWhorfin But that's the point, no? People who post this (or similar) images are trying to say, "Hey, don't be afraid to let in refugees, after all, you wouldn't be here today if the Natives hadn't taken pity on you," when in fact, the lesson of that exchange is that the current residents (Native Americans, in this case) would have been MUCH better off if they had closed their borders and murdered anyone who tried to immigrate.

Also, well stated.
