Yeah, think of the children and as a consequence move the anime to a later time-slot, with an appropriate increase in violence!

This story isn't for children whether they censor out the blood or not.

Just because someone doesn't bleed from being run through with a sword doesn't make the act of stabbing someone with a sword go away. Actually it achieves the opposite of what it's supposed to do.

If a wound bleeds, children will instinctively know it's a bad thing. Show a stabbing without blood and the children will think it isn't all that harmfull and are all the more likely to try stabbing someone in real life.

So censor the act of stabbing, not the consequence of the stabbin. And when I say "censor" in this context I mean an age tag, preventing children from seeing the whole thing in the first place, instead altering the scenes, since it's useless for protecting children and annoying to those old enough to handle the violence.
