He's not that overt. I mainly noticed mentions of violent self-defense being considered justifiable by some Buddhist authors; in addition to his writing in /r/Christianity and his username.

As I mentioned in my earlier post, fascists believe that war is the highest form of human activity. As a result, they want everyone else around them to be willing to engage in violence; but they also know that self-defense is the only justification for violence that non-psychopaths are likely to be willing to accept.

So they use that as a means of leverage. If a fascist can convince you that there has ever been a single instance in the past where violence was justifiable in a defensive context, then in his sales pitch to you for the next war, he will compare the situation there, with the situation in the war that he was able to convince you was justifiable. The usual benchmark that fascists try and use as their model for a justifiable war, was World War 2. This is also the reason why there is so much propaganda related to WW2 on the History Channel, for instance.

They want perpetual war. They want an eventual scenario where America is like the Imperium of Man from Warhammer 40,000. So it is extremely important to them that they can first convince people that WW2 was justified, because then they can come up with an endless stream of threats which they can then claim need to be stopped, with the same level of urgency.

Göring: Why, of course, the people don't want war. Why would some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece? Naturally, the common people don't want war; neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship.

Gilbert: There is one difference. In a democracy, the people have some say in the matter through their elected representatives, and in the United States only Congress can declare wars.

Göring: Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country.
