Well, they're both communities I am/was involved with, although never exactly part of. I was in the GSA in high school, as a straight supporter- something these organizations tend to welcome. I'd be involved here, but it's big enough that I never quite made a place for myself there. And while I'm decidedly not Orthodox, I occasionally attend their services, and interact with them a good bit. Basically, they were two very different communities who I thought were likely to touch on my life.
