@ Panz Fry.

That is the difference between their fruits.. Logia user have the ability to turn off and on their ability. Paramecia's are all about random crazy powers. If you look up the definition of what a paramecia fruit is, it says that it is a " super-human" power which can affect their body, manipulate the environment or produce some kind of substances. Luffy's ability is 'he has become a rubber man'. This is also like magellen, 'he has become a poison man'. If he could turn it on and off, he would not be having constant diarrhea =P Look up the logia definitions and you will see that any body part they control they can turn into that element. Do some research before blabbing shit. (Like I am now hue hue hue) Read the wiki pages of the fruits if you want to get confirmation. :)
