Just recently came off a war ship hunting pirates. I will say this, although I understand where they are coming from and why they are doing it, they also understand the consequences. That said, the only thing that they deserve is a shot to the head. If you disagree, then that is ok, but they won't hesitate to put one through yours.
Stay away, and when in danger, open fire. If you cannot defend yourself or do not want to, then stay far far away. Remember, this is not a new thing.
