The guest does an excellent job of combating the interviewer while keeping his cool. But he makes several mistakes. At one point the interviewer brings up assault weapons [rifles] shorter after the 3:00 mark and the guest corrects him in the definition of an assault rifle. But then soon thereafter, the guest uses that term when talking about semi-automatic rifles. He does this twice.
Now while some people in the gun culture think this is nitpicking and playing with semantics, believe it is not. The anti's have managed to get us, gun people, to use the terms "assault weapon" and "assault rifle" when referring to semi-auto rifles. This was there intent in the late 1980's and they won on this. We have got to stop using those terms when we are talking about semi-automatic rifles.
