I don't know of a nice or easy way to say this but if you get angry or mad at a player killing you in open, no matter what you say, do or think, you are wrong and there's no if's, and's, or but's about it, plain and simple. The player that killed you for whatever reason or no reason at all has done absolutely nothing wrong and is simply playing the game they want to play it. But as some as you, the victim, starts name calling, going to the forums to complain, imagining what the other players personal life is like, ect. you immediately become the only player in the wrong.
No matter how far they set you back, no matter how much your rebuy cost, no matter how many diamonds you just lost, the only way you don't come out of it as the bad guy is if you take it on the chin and maybe send them a GG.
I saw this happen first hand the other night when my PVE buddy and I were on our way to a station to sell the 200+ diamonds we had just mined. I stopped at the station in Irula to store my mining equipment and replace it with hull reinforcements and PA's while my buddy just went ahead with what he already had on his ship. As soon as he gets to the system to sell them he tells me there's a player following him. I tell him to stay calm, put full pips to shields and prepare to submit and pick a system to jump to.
He all but ignored me thinking he could win the interdiction and within moments he was screaming and calling the player every name in the book. I told him to calm down and send the player a GG. He did and ever since has started taking my advice on building his mining ships to be able to survive a player encounter.
All this to say, calling gankers names or even going to the forums to try to convince the devs to somehow remove them is just wrong, period. Gankers aren't out there hoping that you're gonna rage, that just wanna see a players ship pop whether its a fully engineered pvp ship or an unarmed mining ship and if you rage over it, that's on you not them. Although the rage messages do make for some fairly entertaining content on facebook
I think there's definitely a discussion to be had about introducing a simple player bounty system to encourage and incentivize police/white knight players to get more involved and to give gankers at least some slight repercussions for murdering players though.
