> Maybe Citizen and NextDoor's adoption is made up. I don't think it is. People are responding to something. It's not racism.

It is racism, and it's been amplified by news media which selectively report on crimes ("if it bleeds, it leads") and fear-based social media like Nextdoor and local Facebook groups which give a megaphone to every overly suspicious neighbor and self-appointed "neighborhood watch" member.

What's changed isn't the amount of crime. It's the amount of it you get told about.
