Is it wrong to judge how people behaved in the past based on today's morals?

The objection she issued is "Who are you to decide (what I can choose to do with my body or what I must tolerate)."  That's what I've been addressing.  So see my comment above and your answer above.

So in those cases, who are those people to decide?  It's the same thing.  She's not constantly asking "Who are you to decide" is she?
