What are some things that are acceptable in your culture that is frowned upon in America? (Same reverse)

This question is inspired by a chambers post I cannot find of an American asking for the same information.<br><br>&#x200B;<br><br>\*\*Note: I am an Aussie and we do not condone racism in Australia, and I do not condone racism.\*\*<br><br>&#x200B;<br><br>Often I hear Americans say "you do not say that" when a [insert culture] person makes a racist joke about an ethnic group that isn't their own. Usually this is a joke that is light hearted and "racist in the same way that Zoolander was a [insert prejudice here] comedy." I do admit that what is considered offensive does vary on a person to person basis but I have noticed that Americans have a lower tolerance to racism than Australians do.
