I do not understand the attachment to the slogan "Defund the Police". If a slogan requires a much longer explanation essentially explaining "what we really mean is", then it isn't a good slogan. Especially considering there are better word choices such as "Demilitarize the Police".
Ultimately, 'defund' - to most people - doesn't mean reform. Insisting that the vernacular is incorrect is just fighting an uphill battle.
It' probably because "Reallocate and reduce police funding to other resources," isn't as catchy. But yes, I agree, "defund the police," is obviously too vague and means different things to different people. That's the problem with most political slogans like, "Make America Great Again," "Build Back Better," "We Are the 99%," "Black Lives Matter," "Back The Blue," etc. Not really sure what any of those really mean.
Black Lives Matter is absolutely clear and means what it says. When cops roll up and just gun down a 14 year old kid playing with a toy gun based on a whim and "I know I wont get in trouble so who cares" in their heads, that's an organization that does not value Black Lives. It could not be more clear, people just choose to look away.
