One of your quotes intrigued me, "If you can cut your hair, why not your finger? Cuz it hurts?" it reminded me of something someone said to me when I was little. Upon being asked why I was keeping my hair by a 6 year old christian friend (I was around 6 too) I replied by saying exactly what you said. Something along the lines of "Because it is god's gift to us" etc. The boy replied by saying "Then why do you cut your fingernails? Didn't god give you those?" only childern can think of sumtin like that to say, but i didnt really have anytin to say back to that... i'd like to see if you could give me a worthy reply to a childish question thats stuck with me for so long :p
