Of course not. I think it's adorable you like them. Anyone could be a fan.
Who's your favorite??
My friend started watching TMNT when he was like 6 (9 years ago). But then his parents stopped him because apparently it was too "violent".
He still watched it anyway and he turned out fine. He took up karate and all that martial artsy stuff because of them- he's a brown belt now.
