It certainly is good enough for you, if you say it is. It's not good enough for me (and not good enough for people who don't neatly fall into it; luckily for them your simple personal definition isn't the legal definition in many societies), but fortunately I (and you, I assume) are happy existing in a world in which other people have different ideas (many of course are not, and would happily burn people who don't fit neatly into this definition).

Given the problems we see in society, this definition is clearly not good enough for everyone and not good enough to satisfactorily deal with the problems arising; I might wonder what use a definition is if it doesn't actually guide us in solving problems. Perhaps this definition must be compromised when encountering reality in these situations.
