Great thread! I use the argument as well, but not in the absolute sense of "AR15's aren't high powered rifles." It is usually used by me in this context. Generally once a debate on Gun Control starts up, I end up defending gun ownership and the other person will say something to the effect of "Who said anything about banning guns, I am talking about these "High Powered" guns, or "Heavy Weapons" (as per Bill O'Reilly) Or "Assault Weapons" (usually thinking they are class III weapons). To which I reply how do they make that distinction, based on function? Since they are similar to any other semi-automatic in that regard? Is it due to the power of the round, (and this is the part pertinent to this thread) as the 223 round is relatively small compared to what would typically be used for hunting outside of varmint hunting (and then show them a picture of a 223 next to a 30-06.) I agree with many in this thread that for the average non-gun person, they have been so inundated with bad info that you need to start out by just showing them how the arguments they have been making are not grounded in reality. I agree with the post with the Mini-gun video as I believe that is what a lot of people are imagining when they are saying that people shouldn't have AR15s. I think it is important to point out that the gun control issue is not as simple as just banning "heavy weapons".
