Controversy on Japanese Tradition

What are mammals?
Mammals:

a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young. 

In recent weeks there was a world-wide news making event. The event was Japans yearly event for Taijis community's hunting dolphin season. The event is a custom for them for years. 

According to CNN News,

"Although the hunting of dolphins is widely condemned in the West, many in Japan defend the practice as a local custom -- and say it is no different to the slaughter of other animals for meat."

 

Is what Taijis community doing right? Many have a different view on this, what is yours?
