As for the "Defund" thing, it's not just a slogan. Did you watch the linked video? The evidence isn't really on your side there.

I wrote an article about this subject too, if you'd care to look into it and see why it's so important: https://medium.com/politically-speaking/defund-the-police-for-hope-and-change-104e54203775
