If you do not want to be shot, I suggest a transport or a mining ship, to guarantee that you do not.
As for other explanations, I suggest you follow the rather substantial RP on the forums surrounding them. I also recommend you go back about 2 years and take a look at SCRA diplomacy at that period, and once compared you will understand.
Thanks for your concern, but if you die and are barred from the system "you love" for 4 hours, that is not a problem for us, but rather one you should take up with the Admins who set that Policy.
Edit: Oh, and here's another... fun... thought, have you ever contacted a member of the Volkhanists AFTER the raid is conducted to ask permission to re-enter the system? If it is for RP purposes, and not to get your pew on, you might find them very very reasonable in granting that permission.
