It is not a matter of "degree".
A "degree" would be to put George Washington on a bridge crossing the Deleware, instead in a boat, or to change the route to that crossing, so that he passed some visually stimulating historic sites. That "degree" would not change the historical significance of his crossing.
Mrsrs Kushner and Speilberg invent non-historical statements of thoughts, feelings, motives and reactions of actual historical figures as a means to invent attitudes of guilt and shame on the part of those actual historical figures as if those actual historical figures came to harbor remorse for their actions. It is not a matter of degree, it is an intent to lie about the overall view of and about the Isrealis. It is not a matter of degree, it is an intent to change the heart and substance of the entire set of events, beyond the truth, historically, factually or personally, on the part of those involved. The end product, the end view of the whole, not a degree, is a lie and Speilberg and Kushner know it.
