Stoping and questioning why somebody uses DoD or DoW is way more telling than using any of those. Especially that both are perfectly fine, even officially.

A square was renamed in my home city about 20 years ago. We still use the original one usually, even teens know that name. I use a form of the original name of our main stadium which was renamed almost 30 years ago. Heck, some people use names of streets which are not official for almost 40 years now. Btw, the same with departments of the government. Nobody follows how they called at the moment, because nobody really cares. That’s the strange when somebody cares.

By using the actual legal and official name of the department (which Trump didn’t and couldn’t change)?
