In defense of your father on "Defund the Police", the last time I checked, the Black Lives Matter's website where the idea was first widely publicized had a release on it that I was hoping would add nuance to the phrase.
It didn't, at all. It actually reinforced an abolition viewpoint. I went to donate to BLM that day from the Airbnb website's banner, and that release caused me to donate my money elsewhere.
This line got me:
"Currently, we are fighting two deadly viruses: COVID-19 is threatening our health. White Supremacy is threatening our existence. And both are killing us every single day."
Plus (see lack of nuance)
"We call for a national defunding of police. We demand investment in our communities and the resources to ensure Black people not only survive, but thrive. If you’re with us, add your name to the petition right now and help us spread the word."
Oddly, Ben Goldacre of the NHS in Britain (I've met him in the past, and he hilariously stated on stage to a bunch of UK business people that anyone in the audience who voted for Brexit was racist.... the reaction was priceless) has a ton of data showing that black people are dying at higher rates of Covid independent of "deprivation" (UK term for poverty). The position on their website is that it's because of systemic racism. In the US, I absolutely think that is partially correct, but due to Goldacres work, I think it's one variable among others contributing. The added "White Supremacy threatening our existence" is absolutely absurd and overwrought. A little over a 1000 people were killed by police in the US last year. 24% of them were black.

If that is threatening "our existence", then their has been an unprecedented drop in the birth rate for black Americans. (there hasn't been, it's just activists can't do basic statistics and don't care to learn apparently)

Frankly, I think it's intended to be left vague enough to appeal to radicals as well as more centrist types simultaneously.
If somebody from the BLM organization is reading this, I would recommend that they add nuance to the position on their website unless they want to lose voters. My dad was planning on voting for Biden, but the combination of Defund the Police and the removal of Washington/Lincoln/Jefferson statues has pushed him to Trump, who he despises. He lives in a swing state. He tells his friends he's going to vote for Biden, but privately he told me otherwise after calling me about a vandalized Jefferson statue.
For the record, I think that police in the US have become a catch-all for badly needed social services and that reallocating funding is highly desirable.
