The reality is defunding does literally mean completely eliminate to many of the groups calling for defunding. The partial reduction in funding is just a stepping stone. See https://www.nytimes.com/2020/06/12/opinion/sunday/floyd-abol..., an opinion piece titled “Yes, We Mean Literally Abolish the Police”
Note that “defund” and “dismantle/abolish” are separate positions (though many people who hold one as their preferred also view the other as superior to the stays quo, and worse yet while there is a strong tendency in what the language means, the use of each isn't perfectly consistent.)
Which probably shouldn't be surprising since there isn't a single top-down organization behind any of them.
