You know what, I'm going to go ahead and write this out anyway. You're pretty much free to read every word of it or completely ignore it, but take in mind I'm writing this pretty much exclusively for your benefit. The only thing I get out of this is finally getting this off my chest. I'm going to try and write this out in as level-headed a manner as possible, but if it gets Catacomb'd, oh well - at least I made an effort.
So there's a lot of stuff in here that you probably already know, but I feel the need to illustrate my thought processes, so if any of this is old news to you, forgive me.
Let's start at the root of it - Diana Kim, the in-universe character in EVE Online. Diana Kim is not a nice person by any possible stretch of the imagination. She's rude, arrogant, disrepsectful, abrasive, antisocial, violent, spiteful, deceptive, mean-spirited, racist, bigoted, emotionally manipulative, short-sighted, close-minded, mentally unstable, wilfully ignorant, chronically hypocritical and completely irrational - she's essentially a walking collection of personality flaws. Now, this in and of itself is not a bad thing - in fact, observing her from an outside perspective is very compelling given that she's a woman helplessly ensnared by Provist propaganda, clutching desperately to the illusions she has of how the world should be as she slowly watches them become more and more removed from the actual reality of the situation. That's good roleplay material right there.
Where the problem starts is when Diana Kim interacts with other capsuleers. An extremely abrasive, strongly opinionated character like Diana Kim doesn't react well to being told she's wrong and reacts even worse to being shown she's wrong. When people call Diana Kim out on the outrageous things she says, she tends to react with either flat denial or insults - accusations of treason if the relevant character is Caldari, "dirty jaijii" etc. if they aren't. Even at her most polite she isn't willing to consider other people's points of views. This leads to an increasingly limited amount of interaction people who don't agree with her can actually engage in without her either insulting or ignoring them. This eventually leads them to either insult her or ignore her, which in turn further limits the people she can meaningfully interact with.
There is, again, nothing wrong with this in and of itself.
So we get to a point where, eventually, Diana Kim's behaviour becomes so abrasive and insufferable that, in-character, people are no longer willing to tolerate it. Remember that in-universe The Summit is an actual communications channel run by actual capsuleers, and they have feelings and limited patience just like real human beings do. In at least one instance, eventually one the moderators, in-character, got so tired of being called names by Kim that they lodged a ban. Now, again, there's nothing specifically wrong with this.
The problem comes when you, Lithium Flower, the player, become unable to separate Diana Kim's behaviour and ego from your own.
I have noticed, in certain ways, that you act a lot like your in-game avatar. I'm not going to guilt-trip you for this because I do the same. Andreus Ixiris is almost an extension and exaggeration of my own personality to the extent where if this were a slightly less serious setting he'd probably have at least some awareness of it. I have in the past had - and, as a matter of fact still do have - trouble distancing myself from the challenges to Andreus' ego. Emotional investment in your character is not neccessarily a bad thing - in fact, I think some amount of emotional investment in your character is neccessary. However, at this point, your investment in your character is leading to behaviour that is damaging your ability to interact with the roleplay community (i.e. it's getting you banned from The Summit and OOC). Either you have to step back from your character and not take attacks against them so personally, or you need to tone down your character's behaviour and make them more reasonable.
Honestly at this point I think you may have gone as far as you can go with Diana Kim's current line of behaviour. It might be time to have her reconsider her life.
