No, not on HN for reasons stated.
Let's put it this way, our national broadcaster the ABC (Australian Broadcasting Corporation)—our version of NPR—broadcasts material that listeners wouldn't bat an eyelid over—that if broadcast in the U.S. would have to be beeped out (that's if the expurgated version were even deemed fit for broadcast).
I've worked in the U.S., and we see a lot of American TV and YouTube over here and are forever amused at the content that's been beeped out that we'd consider completely innocuous.
I can't think of any U.S. expressions that'd offend here. What can offend is the U.S.'s broad acceptance of gun culture and violence.
