Yeah I always view it as the rights of an individual end where anothers rights begin. Someone who reasonably has to fear for their health and safety do to your words/actions is having their rights trampled. It just gets dicey because people conflate hurt feelings with reasonable means.

If Terry says he really wishes someone put (insert politician name here) through a woodchipper. Terry is venting and people wouldn't without a reasonable doubt believe Terry was going to do that. Now if Terry rents a woodchipper and truck to pull it the next day and starts driving to the city/state where that politician lives... A jury of Terry's peers may suddenly believe they meant to do such themselves, especially since they didn't have any contracts to mulch trees or property they owned in that area.
