The article doesn't state how long he has lived in the UK nor mention how he may be unpatriotic as none of that was relevant to the content. There are white British expats who have children who were born in Qatar and spent their entire lives here, left only to study abroad for university, but then returned to work here, I wonder how often their nationality comes into question?

Sorry, but there is no way of justifying such ignorance as merely a sensible inference.
