There’s been a lot of press coverage concerning the Bruce/Caitlyn Jenner transgender issue. For some helpful perspective, you might wish to read a series of posts on the subject of gender dysphoria written by Christian psychologist Mark Yarhouse (pictured below). The series is on the Limning the Psyche blog, beginning at http://psychologyandchristianity.wordpress.com/2015/01/14/understanding-gender-dysphoria-pt-1/ (follow the links from there to the other parts in the series).
The video of Dr Yarhouse speaking at Calvin College was very informative, well balanced and thought provoking. I highly recommend it. A link is found on Pt. 2.
