Agreed.
If we actually stop to negotiate, we are placing everyone in the ship in much more danger. It won't be able to quickly start moving again, certainly not if we're under attack. Becoming completely stationary will also allow the 60 to 90 hostiles who just threatened to murder us to come right alongside the ship and board it easily. Absolute best case, we're only outnumbered 2 to 1, but it could be as bad as 3 to 1.
If we just keep going, that's not us being hostile or attacking them, either. That's running for our lives.
Opening with death threats precludes good faith negotiation, IMO.
