Great post! So little I agree with, it makes it easy to challenge.
America and Australia are not like other countries where population can trace their roots thousands of years back. On the contrary, they are lands of free and forced immigrants, where populations lived prior to their arrival, by the way.
Each wave of immigrants faced rejection from the less recent arrivals. Irish, Poles, Italians, Jews, Chinese, Central Americans.. name it, they faced discrimination. But no one stopped them on the way in and questioned what value add they would bring to the country. What made a huge difference is the grit, the determination of every immigrant to do better than what they left back home. That was true in the 16th century, it is true today and will be true tomorrow. And it is true regardless of one's skin color or one's cultural background. And a white anglo saxon protestant has no more right to claim ownership of the land than any other immigrant who just happens to have arrived later. In simple terms, one doesn't get to walk in, claim the space and close the door behind them, especially when the land wasn't free for the taking in the first place.
Americans and Australians became lazy with time, getting fat on abundance. America's high death rate isn't due to rapists and murderous Mexicans, it's meth killing poor whites in rural America and crack killing poor blacks in inner cities. The immigrants in the other hand, work their ass off to send money home and build homes and figure out how to stay safe in a country that is so foreign to what they know.
