Well I have to say that I am impressed at your ability to discern the real intentions of entire religious groupings
Actually I don't, that would as bad as condeming any other group on the actions of some. Islamists is usually a generlized term for the more radical. In this case how you define the percentages is up to you.
But I would make a failrly uneducated guess that there are more Islamic people who would like to see Israel gone than there are that don't. In fact I think the last statement is commonly called no sh!t Sherlock. Some of the mild people may put up with Israel, but unfortunitly the percentage of ones who won't is way to large.
