"ANYBODY who gives rank from distance by video, even if you have to show up in person a few times a year, it is only about the money"
That is a very slanderous statement. You must think you are the wisest person on Earth to know the hearts and minds of every person who has charged a fee for martial arts instruction.
Slander denotes the spoken word. It is libel that applies to your statement here and again, you are mistaken.
Anyone who begins a distance learning programme in the martial arts is in the business of selling DVDs, not teaching martial arts. I used to get into this argument with a former teacher of mine who had a similar programme and he finally conceded and admitted that selling videos and receiving testing fees were a way of keeping his studio open and taking money.
Don't get me wrong, if you are an experienced martial artist and want to add to your knowledge and repetiore then by all means buy and view DVDs. I myself have a closet full of videos, books and DVDs. Please do not use them as an instructor. A DVD will not correct you, or push you into training the right way. Doesn't the Kenpo BB creed state "to not [sic] divest the gullible onto unprofitable paths". Let's keep this in mind.
Some people do it the right way however. Larry Tatums DVDs are exeptional quality and he doesn't award people rank through the post just because they buy the material.
You don't have to be "the wisest person on earth" to conclude that someone has produced DVDs for the sole purpose of making money. Using your logic Steven Spielberg produced "Schindler's List" purely to draw attention to the holocaust and the money he made was nonconsequential.
Again, as I have said in previous posts, there is nothing wrong with making money. Just don't do it by deception. Don't promise someone that they will be something that they are cleary not going to be.
Find an instructor who you like and who treats you with respect. If he starts pushing product on you or wants to charge you for merely being in his presence then run the other way and don't look back.
These comments are not libelus, there just opinion based on experience.
