I don't view his past behavior in a vacuum I view it along side current behavior. There is no statute of limitations for bad judgement and mental instability. Bad judgement and mental instability must be proven to have been overcome, else we must assume they are still there.
Is that really fair? They were in college..70's..free love and all that..they were in a relationship, they broke up, tried to connect somehow after, and something happened.
