except for the boomers, its best to shove them out of the way and throw your axe at them from a distance so they don't explode on your comrades.
But seriously....What do we need guns for? Im sure you'll be a fan of this answer....we need guns to live free and protect us from slavery. Need I fucking remind you that you grow weed, therefore, the DEA wants to raid your house and possibly kill you or take you to jail? Maybe you don't grow weed hell, maybe you drank some raw milk, maybe you sold a bong and got tommy chonged, maybe you sold some walnuts....They got submachine guns and tear gas for you Mr Food Grower.
