My 9 year old son thinks GI Joe is tops. He knows it is representative of the brave men who have served this country so well. Anyone who feels victem of a feminine plot has issues. I'll refer you to Jimmy Neutron's buddy Sheen who said "It's not a doll! It's an ACTION FIGURE!!!".
Why is there a character named "Sheen"?
The next year they gave me the "Silver Knight" and his horse. I did like those for the armor and weapons, but they were still centered around a doll.
Any objections against toy guns? I must have dug a dozen BB's out of my hide and don't regret a moment of it. For some reason that never led me or any of my war-play buddies to ever consider a Columbine High type spree.
Chances are your son will be A-OK but I want you to know that public schools and societal attitudes conspire to screw him up.
