If ethnicity exists at all, which it obviously does, then English is an ethnicity. This is a simple statement of fact. It is possible to be culturally English or French or Japanese, etc, but ethnically be different. The first is “software”, the other is “hardware”. This should not be license to be cruel or unfair to people of a different ethnicity. I believe we should be fair to all ethnicities, but not pretend that one or another does not exist.
