They are not there to be your friends StarLord Thief, they are the enemy, the danger, the threat.
I am sure you have played many other games where NPC enemies attack you for no reason regardless of how new you are and kill you easily because you don’t know what you are doing yet, or don’t have the right gear (try playing Dark Souls).
You accept that happens in games. You can’t post on forums asking them not to attack you. You can’t send them an in-game mail asking them why or tell them to leave you alone in local chat. They are NPCs and don’t care.
Just because the role of aggressor in EVE is most commonly other players, that doesn’t mean you should complain about them or be able to force them to leave you alone because you don’t want to be attacked by them.
The players provide the danger and the threat in this game. Stop taking it personally. That’s like getting killed by a dragon in a fantasy game and taking it personally. In EVE, the players are the dragons.
