I was recently re-tagging a question clearly about [transatlantic-differences](https://english.stackexchange.com/questions/tagged/transatlantic-differences "show questions tagged 'transatlantic-differences'") which had previously been tagged [american-english](https://english.stackexchange.com/questions/tagged/american-english "show questions tagged 'american-english'") and [british-english](https://english.stackexchange.com/questions/tagged/british-english "show questions tagged 'british-english'"). 

I decided to remove the two English tags in favour of [transatlantic-differences](https://english.stackexchange.com/questions/tagged/transatlantic-differences "show questions tagged 'transatlantic-differences'").  

Should I have?
