Many posters here use the word "hobbyist" to describe people who practice martial arts that don't train hard, realistically, don't take martial arts seriously, or some combination of these.
Here are some definitions of "hobby."
http://dictionary.reference.com/browse/hobby
Here is one definition from Dictionary.com Unabridged (v 1.1) .
"1. an activity or interest pursued for pleasure or relaxation and not as a main occupation: Her hobbies include stamp-collecting and woodcarving."
With this in mind, wouldn’t serious martial artists who train hard and realistically still be hobbyists so long as we enjoy it and martial arts are not a main occupation? Wouldn’t that mean that those of us who practice martial arts because we enjoy it and whose main occupations are not pro-fighters, MA school owners and teachers, etc are hobbyists? According to the definition given, yes. According to the definition given, the way I described that many posters use the word is an incorrect usage. So why is "hobbyist" used that way?
