Flags Are Not Appropriate For a Language Choice
Many people think it is pretty cute these days to use a flag for a language choice when they are sending over a quick message to work colleagues or to a friend or family member. Many people look at it as a simple short-hand that helps them avoid having to spell out the entire word for whichever language they are referring to.
On top of that, they often see it as a way to add a little fun to the message that they are trying to send. You might wonder what could possibly be so bad about that. However, it is a bad choice to use a flag for a language.
