People abuse children because they're fearful f*cks and it makes them feel more in control. At least that's my experience with my childhood abuse (which wasn't as severe physically, my dad just thought having his children be terrified of him was the way to be a father).
Most women who suffer parental abuse don't go on to be lesbians, they go on to be women with daddy issues. That is all I really have to say on the topic.
