I guess what I was getting at is that English can be removed from culture in certain ways.

Take the situation here in Malaysia for example. English is used as the language of business in the private sector. Hence a non-native learner is taught by a non-native teacher to use English as a communication tool with other non-native speakers. The style of English spoken would be 'Malaysianised' in certain ways. Hence the teacher need not be an expert in the culture of an English speaking country.
