> Some of these, like "grandfathering", cannot even be understood without deep diving on etymology to discover the racist origins.

That one in particular, I was almost offended when I learnt during a DEI training that it could be construed as insensitive/racist of me to use that idiom.

English is not my native language, and is not an official language of my country. I work for a local branch of a large US tech company, and the working language is English, which I'm perfectly fine with. But when we get subjected to DEI training material which was very obviously made for an American audience, even though nobody in this office is a native English speaker, I think it goes too far and ironically becomes slightly insensitive in its own way.
