This is why we blame things on clipdeath - because we don't know the exact hitboxes. Sure, Naut has free rein to say that most "clipdeaths" are actually the player not paying attention, but there's also an element of players relying on the ambiguous "hitbox smaller than sprite" idea. When we're letdown and we get hit, it's only natural to get pissed off.
It's really a simple concept: don't rely on the hitbox, rely on the sprite. If you don't get hit by the sprite, you don't die. If you got clipped by the sprite and didn't die, count yourself lucky that ZUN is showing some mercy :3
If all of you that are whining about the ambiguous hitboxes got your apparent wish and we had perfectly shaped hitboxes that exactly matched the sprites, you would have died doing the exact same thing that the so-called "clippy" hitboxes are doing now. In fact, you'd probably be dying a lot more since all those near-misses (like when Bananamatic had part of those MF bullets pass through him and then clipped on a corner) would be blatantly obvious hits.
And yet if you did what I'm suggesting you do and not get hit by the sprites, neither the current "clippy-death clippy-clip-boxes of DOOOOOM" or the perfectly shaped hitboxes would kill you.
Now, if the hitbox were actually bigger than the sprite I'd say the lot of you would have a valid argument.
