Oxfam have published a New Language Guide (if you google that phrase, there are various news sites and indeed Oxfam's own site) pouring approbation on terms such as 'Mother' , 'biological sex', 'field trip' and even apologising for the fact that the guide is written in English-a colonial language.
There are many more examples-some laughable and some quite frightening.
As Oxfam exists , primarily. to help other nations-many of them non-white-couldn't this be see as a patronising, 'Great White Saviour Organisation' and the next logical step, therefore, is to cancel itself.
