I keep saying that, but nobody wants to listen.

The "proof" from the Usopp fight is one single panel. Not only is there no follow-up to show how Trebol/his body reacted to it, but there isn't even another angle of the same shot. We can't even be sure of what we're seeing, because it's a cartoon.

There are two thick white lines crossing over Trebol's body. That's it.

You can't see rubble on the other side of his body. You can't see Trebol's body turning into his fruit's element as is typical of a physical wound to a Logia. There are white lines. And if you look in the frame before, there are also lines around the spinning shuriken. Why isn't anyone claiming that the shuriken is giving off poisonous spores or something, since every single line that's drawn in the manga must be a literal physical thing?

For all we know, the white lines are just there to show the speed and motion of the shuriken and not the actual physical damage. Maybe the shuriken immediately got caught in his mucus coat and the lines are just a splash of mucus. We just can't know without the full context of the fight.

And that's not to mention the fact that Oda is actively trying to mislead us. It's no accident that he didn't show the rest of that fight, nor that he neglected to give conclusive evidence of either Logia OR Paramecia until this point. It's supposed to be a surprise; that's how writing works.

As for an actual answer, the solution is obvious: wait for the SBS and let the idiots fight it out amongst themselves.
