Here's an interesting contradiction about myself that I've long been aware of:
Politically, I'm very liberal. Temperamentally, I'm extremely conservative. I hate change, I love routine, and I'm so loss-averse it borders on being actually debilitating.
I don't think that combination is necessarily rare, but I always found it an interesting juxtaposition.
But there's another internal tension within myself that I only just realized, and I'm curious if anyone else identifies with it:
I'm very much an institutionalist (that is, I believe in "working inside the system" and think that our major social institutions, even when deeply problematic, can be reformed rather that needing to be burnt to the ground and rebuilt anew). But I'm very much not a joiner.
For example, while my college didn't have a Hillel, it did have a Jewish Students Club (and interest house), which I had relatively minimal contact with. I wasn't averse to it, and I'd go to events and stuff, but I had no formal affiliation with it. I never joined CarlDems, or any of the other political-activist groups on campus (then, as now, my political engagement was done almost exclusively by writing -- I was a columnist for our campus liberal magazine, the Carleton Progressive).
As an adult, I've never really been interested in becoming a "Jewish Professional" (working for the ADL or whatnot). I'm extremely reticent to sign petitions or campaigns, and I've never wanted to run for office. That said, I'm at root a defender of the major liberal institutions in America and in the Jewish community -- the ADLs, the Democratic Party, and so on. I don't always agree with them. But I basically think their problems can be reformed from the inside -- and accordingly I'm generally skeptical of organizations and movements I see as "insurgent" in nature.
Note that I'm not saying that this particular combination -- institutionalist non-joiner -- is a healthy or productive one. Indeed, now that I think about it it seems pretty quiescent (though it's weird to think of myself as politically non-engaged). But I'm more curious if this basic standpoint is one other people relate to.
