The lesson you ought to be taking away from all of this, Seri, is this: If you as a player cannot handle the consequences and repercussions of RPing a particular kind of character, you should not be RPing that particular kind of character.
You play a character that is known, widely, to be (or have been) an arrogant, disrespectful, inconsiderate, womanizing prick. Even to the people who for some reason decide to give him a shot on the off-chance he's only like that in public and that it's just a front. Good for you. It's great that we have that kind of character running around, because you're right - it would get pretty boring with nobody ever getting mad at or fighting with one another - but you can't, in the same breath, complain that people don't want to RP with you on that character, and not expect to get laughed at. Most people do not like being around that kind of person in real life. How then, is it unrealistic or unreasonable, for our characters to just ignore it for the sake of giving you something to do? We're playing our characters true to themselves: it would be breaking our immersion and RP to do so, just for your sake. It's not going to happen.
You often make comments (more like complaints) about how some of us (me, for example) play overly likable characters that get away with a lot of friendships and relationships they, in your eyes, should not be able to get away with. I think you are getting the difference between liking someone and respecting someone mixed up. Liking someone is not a prerequisite for respecting them, and should never be one. Yes, Morwen has a lot of friends in a variety of seemingly-contradictory places, who, put together into one room, would probably result in a hell of an incident report for the police. But she also has a fair number of enemies and rivals from a variety of places as well. Many of Morwen's enemies still respect her to some level or give such an impression, even if they don't like her, and in many cases the reverse is true.
I told you the other night, in response to some complaints you were having about certain characters avoiding you, that I felt the problem was probably with the way you approached them. Asking people out on what amounts to an "entry-level date" is not a productive way to go when your character has the reputation described above. You come on too strong, and it's just not appealing to some people, who will then retreat and remove themselves from a situation they aren't comfortable in. When those characters happen to be friends with other characters who have had similar experiences with Seri, it should come as no surprise to you when that is the reaction you get when you don't change your fucking playbook.
But a lot of this is beside the point: it wouldn't bother most people, if their characters' reactions didn't bother you so much that you felt it necessary to complain or take the piss about it on a regular basis.
Anyway: to answer your question more directly, the answer is yes. There is a point to playing Seri. It's a character archetype that is sorely needed in many respects, because the lack of it is unrealistic. However, I do not get the impression that you are able to handle playing the part of that archetype and the responses it gets without being able to keep it from bleeding through.
