Let’s have a look at what the church teaches for us Catholics.
2263 The legitimate defense of persons and societies is not an exception to the prohibition against the murder of the innocent that constitutes intentional killing. "The act of self-defense can have a double effect: the preservation of one’s own life; and the killing of the aggressor. . . . The one is intended, the other is not."65
2264 Love toward oneself remains a fundamental principle of morality. Therefore it is legitimate to insist on respect for one’s own right to life. Someone who defends his life is not guilty of murder even if he is forced to deal his aggressor a lethal blow:
If a man in self-defense uses more than necessary violence, it will be unlawful: whereas if he repels force with moderation, his defense will be lawful. . . . Nor is it necessary for salvation that a man omit the act of moderate self-defense to avoid killing the other man, since one is bound to take more care of one’s own life than of another’s.66
2265 Legitimate defense can be not only a right but a grave duty for one who is responsible for the lives of others. The defense of the common good requires that an unjust aggressor be rendered unable to cause harm. For this reason, those who legitimately hold authority also have the right to use arms to repel aggressors against the civil community entrusted to their responsibility.I’m not overly concerned about this preacher or anyone else’s opinion since he’s like most other non-Catholics and uses his own personal fallible Biblical interpretation as his authority.
Since it’s his fallible interpretation and I choose to adhere to the infallible interpretations of the (far and away more educated) infallible teachings of the Catholic Church I can look at it with a better perspective and handle this issue accordingly.
As for everyone freaking out about gun violence and who thinks disarming us all is the answer I would have to suggest that you acquire a copy of
Resistance to Tyranny: A Primer

…and take careful note of the fact that nations that have done that have proved to be the ones where freedoms are most restricted and in fact where genocides and tyranny have grown most powerful at the cost of the lives of citizens who would otherwise been able to offer an armed resistance and perhaps even prevent those same murders.
Keep in mind that Hitler and Stalin both disarmed their people…and that has worked out really well.
