I figured he could've meant that, but responded what he said.
If you assume he meant what he said, he implies that having guns and knowing how to use them is training and equipment for murder. The latter is potentially true, but is also potentially true of an absurd amount of things that aren't firearms. All of which have potential uses outside of murder. The former is simply untrue. On no occasion does training on the safe use of guns train you to murder people, and anyone with any experience with firearms knows that.
If you assume "civilization is here so that I don't need to be trained and equipped for murder" means "people shouldn't fear being murdered in civilized places", mind you two statements that mean entirely different things, both normal enough to be read literally, then he has a point. But, as you pointed out, StarSlayer, a weak one.
And if Turambar was talking about himself alone, there's really no reasonable point anywhere.
