robtek, the problem arises particularly when it is not apparant as an opinion but presented as facts. That is exactly the problem with the handbook. If they had written: In our opinion this happened this way or that way. But that is exactly what they did not do.

As I think you are a very intelligent guy I think you know that by omitting certain information or by using specific argumentation and phrases things can get a very different meaning and direction.

The easiest thing for them would have been to just leave out any historic background in the leaflet or referred just to a short timeline. But they decided otherwise and wrote their vision of things there in a very particular way.
