Well, I think it should be illegal to make things illegal just because someone doesn't like them.....

quothe the idlemachine: " 'He who fights with monsters should look to it that he himself does not become a monster.' Or how about: 'Two wrongs don't make a right.' Because how you win is as important, if not more so, than winning itself. I agree that there are times that we need to fight but we also need to be sure we don't lose ourselves in the battle" Spoken like a person who has never engaged in a REAL battle. Fighting "fair" is for Boy Scouts, (who can no longer use the name) and the Marquis de Queensbury, (who is dead). If the battle is worth fighting, I would submit that it is not only permissible, but all too often necessary to "lose ourselves in the battle". The 'moral high ground" is for losers and preachers. The warriors will accept mere victory.

Rifle choice depends on the battlefield. In a desert war, with engagement distances in the hundreds of meters, hell yes, give me an '03A3 over an M16.
In an urban warfare environment, not so much...but maybe a Benelli M1!
