That has always been true, and for everywhere. However very few countries are anywhere near as accepting for foreigners as the US as a whole despite the many who are not. Canada is just as accepting from what I can tell - I don't know enough about Australia to know. Most other countries are far worse - though many will not admit it just how bad their country is.
Sadly Australia is very welcoming to foreigners until you get about 50km out of the major cities. Our xenophobe political party (One Nation) has had a significant rally in the last few years, to the point where by some measures it is the second largest party.
