While I understand the emotionally-driven "well let's just ban everything" responses, they don't make much logical sense. It's not whether something is simply unorthodox or unusual. It's whether it's use becomes so popular that it threatens to eliminate the traditional style of play. When unusual styles become so popular that they become the first and only style a player is taught (which is happening now with some young players and the anchored stroke) then it threatens the traditions of the game. The damage is only made more obvious when people argue that it's not fair to ban the anchored stroke because that's all that some players have ever used. That statement only strengthens my point.
I realize tradition doesn't mean anything to some people. I'm guessing some golfers would love it if the USGA would stay out of the equipment issues. Maybe you'd like it if the USGA allowed manufacturers to create golf balls and clubs that always went straight and allowed you to drive every par 4. Wow, wouldn't that be fun. Imagine golf balls with gyros and GPS so you were guaranteed a hole-in-one on every hole. If that's really how you feel maybe you should stick to Tiger Woods Golf where you can change the spin of your ball while it's in the air. Is this the problem I wonder? Have golf video games made the game so easy that if people can't play as well in real life then they want to create equipment and methods that can make them better without the challenges that traditional golf offers?
The argument that "well maybe they should ban everything" can easily be countered with "well maybe they should allow everything", couldn't it?
