The fact that you seem to expect increased respect because of controversial opinions

This is not what I expect. I expect increased respect for having thought through ideas. I also expect that most people have come to conclusions differing from the LW mainstream on some ideas, and expect - or at least hope - that a willingness to express this is something respected.

that you when you wrote about your support for infanticide, you were motivated more by the fact that many people disagreed with you, than by the fact that it's actually a good idea that would make the world a better place.

The reason I chose to write about infanticide, as opposed to my position of Newcomb's paradox (one-box) - or more illustratively my position on the general shape of planet Earth (roughly a sphere), is that my position on infanticide is controversial and therefore more likely to prompt interesting discussion, whereas my positions on Newcomb's paradox or the shape of planet Earth are not. So yes, the reason I chose to write about infanticide was that many people disagreed with me, and in fact I was explicit about that in my original post. This does not mean I hold this position to be deliberately contrarian, and implying otherwise is insulting.
