exposing people based on their religions so they can be taken off to slaughter with exposing people based on their decision to join a hate group that seeks to exterminate a race or religion?

Is that really what you're doing here?

David Clinton Wills, a visiting Professor at NYU who follows social media, says he's actually troubled by the way that anti-racist activists are using Twitter. "Never in my lifetime did I remotely think I would vaguely defend the rights of a possibly very hateful person," says Wills who happens to be black and Jewish.

Nonetheless, he says "it scares me to call that activism because it seems more like a certain condemnation and a certain judgement that ironically flies in the face of democracy itself."

Wills sees a lynch mob mentality on both the left and the right when they try to use social media to shame people.

Just last week, Google was at the center of another social media storm when a memo by a company employee critical of diversity efforts at the company went viral. When Google fired the employee web sites on the right, critical of the company's actions, released names of Google employees. Those employees were then harassed online.

For Wills the historical parallel is Nazi Germany. Wills says the Third Reich encouraged citizens to name people they thought were enemies of the state. "When that became a power that your neighbor could execute or your neighbor could use against other people the power became unchecked."
