Sorry but this is not true. The word vain in Hebrew means “empty” “worthless” “Nothing” or “For no good purpose”. Using His name in a way that serves no good purpose is wrong. However this command is most likely also specifically talking about the proper name of God “YHWH”. But in the end its all about where a persons heart is at when they say something anyway. Arguments like the one you put forward only excuse behavior that doesnt really edify us anyway so why not try to maintain a holy heart in our speech as well. After all James tells us that the tongue is the rudder that controls our whole body.
