If that KKK leader then handed out a list of people a list of people to kill, I suspect it would be a VERY different situation than vague and non-specific talk of vengeance. Specifying targets, especially in the wake of a highly publicized assassination, is not abstract.
Adding in what Idlewords posted below:
"The guy also posted "the CEO must die" to his Instagram."
Provisioning a hit-list in the context of a call to murder the people described isn't abstract or vague either. At best it's a terroristic threat.
