Yes, actually I do interpret it that way. I see it as claiming that Jesus commands his servants to slay those who refuse to have him reign over them.
And yet that has not been the Christian interpretation, it is not the position of any exegete either in antiquity or today. On the contrary, the unanimous position of the Church for the first several hundred years was that violence was, under no circumstance, acceptable. And when the State became, nominally, Christian and the use of violence was controversial, and official ecclesiastical response to the State's use of violence against pagans and heretics was anything but universally accepted; when Priscillian, the first heretic executed by the State, was executed the immediate response from a number of leading churchmen (including Siricius of Rome, Ambrose of Milan, and Martin of Tours) was to condemn the act.
To go from universal condemnation of violence to the acceptance of violence didn't happen over night, but was a transition that occurred as the Church adopted a position that, first, Rome was divinely ordained as the civil protector of the faith to (in Western Europe with the fall of Rome in the 5th century) to the emerging feudal states, in particular with the crowning of Charlemagne and later Otto. With this theological accommodation the State was no longer perceived as an antagonist, but as the Church's worldly ally--which was relied upon as a source of temporal protection and, far too often, as a means of crushing opposing ideas: heretics, pagans, Jews, and eventually Muslims as well.
I don't believe there is any justification for this accommodation, I can understand why Christians, once becoming accustomed to protections under the civil law would become comfortable with it (after all, it's human nature), but the acquiescing to stately violence that accompanied this transition is deeply immoral and wrong. And we are still suffering from it today.
When the Church makes its bed with the State, the Church always loses. Because when the Church betrays her teaching and mission granted her by Christ, she has lost.
