On Tumblr (and even in real life), a new form of extremism has been making itself prevalent.
They call themselves "Social Justice" bloggers, and claim to fight for the rights of marginalized, underprivileged groups. Unfortunately, in doing so, they resort to lashing out on "privileged" groups - whites, males, straights - and subject members of these groups to death threats.
The FBI states that a hate group's "primary purpose is to promote animosity, hostility, and malice against persons belonging to a race, religion, disability, sexual orientation, or ethnicity/national origin which differs from that of the members of the organization."
Therefore, WE THE PEOPLE demand that the Department of Justice treat "Social Justice" extremists on Tumblr as a collective hate group.
