It's quite difficult to avoid a debate when you're opening statement itself is debatable, ie "majority of educated people agree." I would guess the majority of "educated" people (what does educated mean? high school? college degree? something else?) have not actually contemplated what the phrase "historical truth" means.

Actually I think you can be quite uneducated and understand what is written in wikipedia.

By the way I think that the definition you've presented would classify several religions as historical truth.
