I can understand liking Naruto, as long as you accept its faults, and dont go around claiming its the best anime around.
My favorite anime is Bleach, but I dont say to people its the best anime, my username is not a bleach character, and nothing about the show is in my sig or blogs, though I might mention it as apart of a list of what shows I like in my blog. I like many american shows better than Bleach, im a casual fan.
For Naruto, If you realise the main character is retarded and wants to be the ruler of a shit village, and that the shows concept of what ninjas are is compleatly off, and your not defensive of the show, than your fine.
