"Many have asked why this would not work fof DADT."
Because they still get kicked out if they ARE asked or DID tell. It's not illegal to ask or tell. I got enough harassment because people believed I was lesbian. If it wasn't against any policy to be truthful about one's sexual orientation, perhaps there wouldn't be those 'passing' to escape the bullies or people's suspicion.

People shouldn't be forced to 'tell', but they also shouldn't be forced to be secretive. Harassment of people who choose to be honest should be against policy, and punished accordingly.
