My grandson Julian, who lives with me, he is all about guns, bombs, grenades, tanks, military planes, boats, plastic army men, toy guns, camo fatigues. When we go to the library, he always includes books about military stripes, patches, medals, uniforms, ships, boats, tanks, planes.
He's the best kid, too. Not violent at all. He still designs tanks, guns, etc. at least three days per week.
My son? I named him after Jesse Colin Young of the Youngbloods because of the song Get Together, an anti-war song from the 60's. I never allowed him to play with guns, even cutting the guns off the cowboys I would buy for him.
He has grown up to be a gun toter and has the most angry temper.
