What happens when someone invades your country? Do you sit there and just scratch your head in awe? No? Oh right, you shoot them and fend them off.
Core are enemies of the AI, you came into the AI home space, Planet Gammu of all places, you shouldnt have expected a fair fight. All you want is your crap pvp urge satisfied, ok, next time I bring an Onuris into Rho i want only 1 ship to log to stop me and if its not a Core light fighter (cba for name) then prepare for the room to smell of hypocrisy.
