The new rule proposed by golf's governorning bodies would eliminate the anchoring of belly and broomstick putters and is exactly the same as if bowling decided to ban 2 handed deliveries.
People claim that anchoring the putter is a competitive advantage, but this is 100% false. It cannot be a competitive advantage so long as EVERYONE IS ALLOWED TO DO IT. If anchoring the putter is so great, Tiger Woods, Rory McIlroy, and anyone else is welcome to use it, just like 2 handed bowling.
I have heard the argument "the people who go to belly putters are the people who have no success with traditional putting." ironically this statement came from a 2 handed bowler who had little success 1 handed and then started winning once he went to 2 hands.
I have also heard the argument that traditional putting brings nerves into play more - so does 1 handed bowling: if your thumb isn't in the ball, but your other hand is, it becomes pretty hard to squeeze or drop it under pressure.
You're taking away an element that makes the game far more enjoyable - and if you want to grow the game of golf, you need to WELCOME the style just like bowling has.
And before people start telling me I'm biased: I bowl 1 handed and putt traditionally.
