Okay, enough with being polite.

Logias cannot be hit by physical attacks. Period. It's got nothing to do with whether you hit them unaware or not, you cannot hit Kizaru in a state where he's 'normal' because he's a logia, it'll go through him no matter what, unless you use haki.

Neither Kizaru nor Enel has shown any proof of being about to use haki, so don't even try to argue in that direction.

There, now stop using stupid arguments that's not only pointless but also entirely unfounded.
