I dont think it is a big issue. Most people have an awareness of how other countries talk about things. I live in Australia and I know that diifferences are inevitable. I know that many medications on this site have a different name to where I am but it is okay. People are becoming educated about the differences.

Take for example the term biscuits. The US calls them cookies. As time goes on it is more common to hear the term cookies being used over here. Another word here that was used very often was insects. We didnt call them bugs. A number of years have passed and the term bugs is now heard more than insects.

Language has a way of morphing over time and countries.
