I've found this presentation by Ted Cox, a straight, ex-LDS writer who went to a JIM weekend undercover and shares his experience and interpretations, pretty interesting, although he does tend to fall into the tendency to dismiss ideas based on personal choices of certain of those who espouse and promulgate them, and he clearly has a bias. But so do the creators of JIM, so...y'know. One thing I find interesting is that I've found myself nodding at many points but saying, "Eh, now wait a minute, that's not entirely on-point," at others.
If you're uncomfortable with some crude language and humor, you might want to skip over the first 2 1/2 minutes. In fact, up until about 4:45 of part 1 is just intro stuff that's not necessarily relevant. There's incidental language throughout the rest, but nothing too in-your-face, from what I've seen in the first 6 parts so far. To get to the rest of the parts, either watch this until the end and follow the links in the video, or click on the video to bring up a YouTube page with some of them listed on the right.
