What i get from your reasonig (and i could be wrong) is the fact that you want to call "other" terrorist before call the "so called terrorist" with that name. So be it if you like, but then please don't deny the fact that Bin Laden was a "terrorist".
Oh well deny it if you like.
P.s. The examples you bring, althought correct, are 60 years old, and the world is changed by chance
