I hope you forgot the sarcasm tag nothing that anyone says that is offense can justify a false accusation of threatening someone with a weapon.
And yet, it happens. Such is the danger of living in proximity to the mental disorder known as Liberalism.
I beg to differ.
The host could have said something in jest that was perceived as a direct (but understated) threat on the life of one of his guests. Doesn't mean he meant it that way, but perceptions vary widely between different people.
People take things the wrong way all the time. Normally it doesn't result in a situation getting as out of hand as this one did, but it does happen.
Again - we're left to surmise the basic facts of the story, because the reporter left them out.
