Not that Silvers claims are likely to be true, but why would you find it dictatorial of a president to fire a military person for openly claiming not to be prepared to follow the oath he took for service?<quoted text> Sounds dictatorial and outright evil to me.
If a citizen is a foe of America, it is the military servicepersons oath sworn to defend America against them. If that means shooting them, then that is what he must do or else be fired for not upholding his oath.
Note Silver or the person who actually makes this claim does not refer to the situation the shooting may have to occur in. It is all just playing upon your ignorance. They tricked you so easily.
