My reasons for thinking we're a perfect match:
1) Point: We need a challenge; everyone else is just too easy to win over.
Personal experience: When friends ask me how I do it, I shrug and say something banal because it is useless to try to explain. I feel that “game” is a skill that is fine-tuned throughout life, and even a lifetime of practice will not be of desired effect unless one already possesses an uncanny knack for reading body language, understanding weaknesses and individual needs, deciphering subliminal clues people unknowingly give off, and minimal emotional involvement. The ease at which I get what I want can actually be frustrating. I usually lose interest right after I acquire my target's complete attention and/or whatever I need from him. As I slowly let it go (so as not to burn bridges just in case I ever need that bridge again), I usually get some sort of a love confession. It’s a nice ego boost, but it honestly annoys me. Maybe it annoys me because it reminds me that I am incapable of feeling anything back. More likely, it’s because I have to waste my energy trying to let him down easy. Yet even more likely, it's probably because it reinforces the fact that I'm failing in my search for another of equal mindset.
Rationale: Dating another sociopath would be much more invigorating, as it would be a constant challenge for one another’s attention. As stated in Robert Greene’s “The Art of Seduction”, the most successful couples are those in which both people have mastered seduction. Without this, we get bored. We need a game, and an incompetent opponent is no fun after the first round.
2) Point: Save the emotional acts.
Personal experience: I do manipulate, but I do recognize that if I want to remain in respectable societal standing, I have to play towards the emotions of the people I deal with. In my past relationships, I have had to fake what I am not feeling (i.e. pretend to comfort the guy when he’s upset, force myself to do the whole stare-into-each-other’s-eyes thing, convince him that I feel the same way, etc.) I’m not sure if there are other socios out there that feel this, but strong expressions of love and sadness are the two emotions I feel the most phony mimicking. I can literally feel the insincerity seeping out of my pores. Near the end of relationships my tolerance for such acts fizzles out, and I am accused of not caring…and since I generally don’t, he ends up hurt. While I have never felt sorrow or regret from this, I also do not want to leave a trail of broken hearts behind me. It’s essentially damaging my reputation and whatever connections I might need to make in the future.
Rationale: Tending to a lover’s emotions is tiresome and an enormous waste of time. Dating a sociopath would eliminate this rollercoaster of ridiculous emotional performances, and we would be able to live in drama-free harmony. Paradoxically, it would actually be a more honest relationship.
3) Point: We are attracted to those who are both book-smart and street-smart.
Personal experience: I am attracted to intellect and power, and I assume that most other socios are as well. I’d rather marry an ugly but manipulative and successful genius than a sexy-as-hell but dumb-as-a-rock superstar. I saw that you mentioned the 48 Laws of Power. I cannot discuss this book with anyone I know. They lack the ability to see the rules as one entity from which we must derive certain principles, based on what our situation and goals are. I consider craftiness along with the ability to gauge situations and handle them with appropriate tact to be my definition of "street-smart". Lacking this quality is a complete turn-off for me. Being book-smart is also essential for my attraction to another; if I feel that I am capable of getting better grades on a factually-based exam than someone, I can't take them seriously. In my dealings with dating, I have come across only one person who has mastered both areas. I have insincerely told several people throughout my life that I "love" them (usually out of obligated reciprocation); I'm unsure of what my take on love is, but I can honestly say that what I feel for that one person is closer to love than what I've felt for anyone else.
Rationale: There are plenty of book-smart people out there. There are also plenty of street-smart people. To have both is rare- and those who have both have an edge over everybody else. Most socios are able to recognize this potential for success, for they possess it within themselves. Naturally, we are attracted to excellence. Therefore, we are attracted to other sociopaths.
4) Point: Being a "chameleon" can only be understood by others like us.
Personal experience: I change my persona depending on what I need and who I am around. My groups of friends are eclectic and from all walks of life. In the past, when the guy I'm with at the time has met a group of friends who views me differently than he does, disaster ensued. "Who are you?", "You didn't tell me you used to do such-and-such things", "I talked to so-and-so...I don't even know you", and so on. I am forced to purposely avoid letting my significant other meet certain people or hear certain things, in an attempt to maintain his view of who I am to him.
Rationale: Who we date is usually a frequent escort. That being said, it is difficult for someone who isn't a social chameleon to get along with more than one group of your friends- or anyone who sees you in a different light than your lover does. Dating another sociopath means that he/she will easily fit into your eclectic groups of acquaintances. He/she will understand the necessity of mimicking and will be able to recognize when it is being done. He/she will also be able to mimick, which eliminates the "why do your friends hate me?" mediation and the "what was that all about?" explanations. He/she will understand that the "you" that you are pretending to be is just an act.
I could probably continue, but I'll wait for some feedback first. Please do note that I am presenting this from theories I've derived from my own experiences. Also note that I am not referring to full-blown psychopaths, sadists, or those that might only date to extort things from/harm the other. Rather, I am referencing "mild" sociopaths like myself, who understand self-interest and are frustrated with dating simpletons.
