1. Of course for violent / forced rape father's rights are terminated (going by layman's terms of forced / violent - I know that by definition, rape is forced)
2. If the lady is found to have raped the man, her rights should be terminated
3. If it is not so clear cut (statutory rape of a 17yr old for example) then it needs to be taken on a case by case basis
4. If it is (non violent) date rape or rape of a drunk (but not comatose) woman, there is nothing that would automatically make me assume the father is not fit to be a daddy (although the cards would be stacked against him, and he would need to prove himself fit)
