rh200,
You say
and then you do:
there are more Islamic people who would like to see Israel gone than there are that don't
Islamists is usually a generlized term for the more radical
No it isn't ->
Islamist - definition of Islamist by the Free Online Dictionary, Thesaurus and Encyclopedia.
And if it was (or if that is your as-yet unstated definition of it) then your reasoning would be entirely circular. You'd basically be saying "hardline radicals want hardline radical policies to succeed" - I believe that one really does come under the category named for the exclamation aimed at Sir Arthur Conan Doyle's creation.
I would make a failrly uneducated guess
You said it. Perhaps a bit of information would be preferable to "uneducated guesswork" when trying to discern whether "the percentage of ones who won't is way to [sic] large"?
