When I lived in Asia. I would bow to people, be extremely deferential to my superiors, and avoid saying any original thoughts out loud in any situation where I was not the highest status person. I didn't do this because that's Really Deep Down Who I Am, I did it because I read a book on dealing with Asian people, and that was what you were supposed to do. As a result, I got along with the Asians I knew and had pretty good relationships with most of them. If I'd been completely direct and honest all the time, the Asians wouldn't have "appreciated my honesty". They'd have fired me from my job and stayed away from me.

I don't feel guilty for "manipulating" any Asians. I did what I had to do to be successful in Asia, it made me happy, and it made the Asians who worked with me happy.

I interact every day with two groups of people whose ways I find even stranger than the Asians', those being extroverts and women. I basically coexist with extroverts the same way I coexisted with Asians; I read books about their behavior, I figure out what I need to do to get along with them, and I do it. Do I wish I could win their friendship solely by being myself? Yeah. But that was what I tried for about fifteen years, it ended up with me being unhappy and friendless, and instead of me blaming the extroverts for it I decided to learn techniques to get along with them. I think it makes us all better off.

I have split feelings about the seduction stuff. As a "how to trick stupid girls into sleeping with you so you can dump them later ha ha" sort of thing, it is clearly evil. But when I think of it as a guide to dealing with romance in the same way I've already used guides to dealing with Asians and extroverts, well, I could kind of use something like that.

I guess the difference is that the only thing I consider morally wrong is making other people unhappy. To trick a woman who really doesn't like me into having a one-night stand she'll regret later - that's bad. But if there's a woman whom I think I could have a really good relationship with that would make us both very happy, and the only thing stopping her from going out with me is that my body language is unattractive and I don't know how to ask right, then I wouldn't feel too bad about counteracting the stupid tricks her brain is using to prevent her from going out with me with stupid tricks to make her want to.

(disclaimer: this is all probabilistic. There are a few Asians, extroverts, and women whom I have a much easier time getting along with, but in general I find these categories of people harder to understand.)
