"Being socially exposed is AOK when you hold a lot of privilege, when people cannot hold meaningful power over you, or when you can route around such efforts. Such is the life of most of the tech geeks living in Silicon Valley. But I spend all of my time with teenagers, one of the most vulnerable populations because of their lack of agency (let alone rights).
Of course, teens are only one of the populations that such exposure will effect. Think about whistle blowers, women or queer folk in repressive societies, journalists, etc. The privileged often argue that society will be changed if all of those oppressed are suddenly visible. Personally, I don’t think that risking people’s lives is a good way to test this philosophy. There’s a lot to be said for being “below the radar” when you’re a marginalized person wanting to make change.
