Deletion of Colonial preference

Comment: to Imperial Preference. I have read the discussion on the talk page, but was unconvinced because of usage in reliable sources of both terms primarily w.r.t. the British Empire, as here:https://www.jstor.org/stable/pdf/2141881.pdf. If there is a difference, Colonial preference should be deleted as it fails . Yet my view is that any more general usage of the word is appropriate in the Imperial preference article, because that is where many readers would find it. Having reached that conclusion, I read Peterkingiron's analysis above, which makes the point better. In terms of answering a potential reader's information requirement, a redirect is required
