I wouldn’t call it a mistake but it’s kinda unnecessary for the people outside of US. I won’t deny that it can be useful for people from US though. However mistakes can happen when one don’t check for which community they’re on, it’s quite normal.
The opposite was happening on Reddit. The title didn’t mention the Georgia as a state but the news was about the state, on world news sub. Easiest way to prevent this misunderstanding is to use the title accordingly.
