I think I misread your previous statement. I see you were saying that if we have armed citizens, the offenders will only use methods that don't get them shot, so bombings and other "assailant not present" offensives.
I think, however, that it's a bit of an absolute statement, as even skirmishes in the combat theaters still heavily rely on small arms from both sides. Perhaps it is possible for that to become the world we live in, however I don't see that being the case given past history.
Keep in mind the idea of an armed populace isn't a one dimensional outcome to only defend against terrorists, but as an equalizer against any assailant in a life or death situation, be they foreign or domestic.
I just want people to have the option to defend themselves if they choose. In this case, the French people did not and do not have that option. Gun laws in France makes NYC look like a paradise for gun owners.
