And who exactly would him and his musket be defending them from? If a person is born in New Zealand, has parents / grandparents from Samoa and ends up living and playing in England it is entirely believable that they could have a desire to represent any of the countries. Having been born in England to English parents the only country i would have a desire to play for would be England, but that doesn't mean i want to stop others representing the nations they feel a connection to.
