I don't know how common it is among Christian belief, and there isn't any consensus, but there are people who say they think there's hints Ham raped Noah. Personally I don't see it, but it is a theory. It's explained here:

Not around so much now that school's started
"Live a good life.
If there are gods and they are just,
then they will not care how devout you have been,
but will welcome you based on the virtues you have lived by.
If there are gods, but unjust, then you should not want to worship them.
If there are no gods, then you will be gone, but will have lived a noble life
that will live on in the memories of your loved ones."
Marcus Aurelius
