Yes, my 1950s history books were biased in what they put in and what they left out, and in the interpretation.
But Hollywood has pushed the envelope. Consider Robin Hood. The facts are clear. The king was away fighting a war in the middle east. The war was sucking all the tax money.
The Sheriff of Nottingham was without his normal tax money. So he stole the grain, chickens, livestock and silverware of the middle class. He would have stolen it from the poor ... except the poor did not have anything worth taking.
Robin Hood and his Merry Men returned to their rightful owners the property that the Sheriff had stolen.
Robin Hood did not steal from the rich to give to the poor. Robin Hood did not steal. The Sheriff was big government. Robin Hood was against big government.
Back to Robin Hood, if we want to correct the record it will require highlighting the turning point. See this:
One side will gladly say something is true and the other will gladly deny it, but only those who can contrast the before, turning point, and after can put the issue to bed.
