Marla Wilson, 35, of San Francisco, said she was appalled when she saw white supremacists marching so brazenly in Charlottesville. Doxxing, she believed, was an effective way to make people think twice about being so bold with their racism.
By actively participating in the march a person marching can be assumed to believe in what the marchers are promoting; a danger would be to dox a bystander who may be observing, or protesting the march.
