Unfortunately, this is a case where words really matter, because that is exactly what the word Defund means.
If you must explain that the term really means something different from what its dictionary definition is, it is the wrong term. Reallocation of Responsibilities, or Change Police Functions, would have been more descriptive. Anything but “Defund”, which hands opponents a perfect weapon. They don’t even have to think.
Otherwise, I fully agree with everything here.
