If someone directly threatens you or someone else online, report it. They should take it seriosly if it is a direct threat with a sppecific victim.
With the registries growing so rapidly, it won’t be long before those expressing violent desires towards registrants have a family member or friend on it, if they are not on it themselves.
I try to remember that those who lash out with such rage at others who make them uncomfortable are often merely trying to cover up something they hate about themselves.
