I did not misread. Let's just say that at twice your age, I have a larger outlook than you do. No one would ascribe that letter to a "strong, beautiful, decisive woman", they would say it was written by someone who rides a broomstick. As far as your husband's hatred of his parents, you will be building bridges for them very quickly. Blood is thicker than water, as they say. A strong, beautiful, decisive woman is loving, not hateful to the people in her life, and she would not be threatened by a cookie for breakfast. Nor would she blame a child's tantrum on another adult.
I don't have a thread of my own, I sometimes write my thoughts on Sara's thread, as she is no longer on DB, but she had a lot of good advice.
