Lol im sorry, so they just have all the makings of a nutcase then?
"Your honour, my client is no danger to the public providing he is not approached, touched, spoken to, refereed to, looked at, and no valuable items are in his vicinity."
Your right guys lets offer them tea and biscuits i see no hostility from our civilised alien friends.....
I get the feeling you're looking at these new additions as nothing more than 'things to shoot at', rather than being part of a storyline. Just because an entity would rather you didn't encroach upon their space or act in any way aggressively towards them, doesn't mean they must be shot at.
Hostility is not even the same as aggression. Hostile means that they don't want to be disturbed otherwise they will attack. Aggressive means they will simply attack you regardless (I'm simplifying here, because I can't believe I'm having an argument about something that was supposed to just be a bit of RP fun...)
