Given that transgender issues have only been so recently brought up in Western discourse, very few denominations have commented about it. I know Methodists don't have a policy, for example. Oddly, from what I can find, denominations have been a good deal more quiet about transgender issues than LGB ones; conservative Methodists basically
forgot to bring it up at the 2008 General Conference.
This hits pretty close to home for me.
Being transgender, like sexual orientation, has spectra involved in it. I can't speak for people at different points on them than I am, and obviously my experience at a somehow-thriving mainline church in Western Massachusetts is far from typical, but insofar as my gender issues (since I'm at an extremely early stage of this whole matter mainly out of fear or inertia) have ever even been mentioned I've experienced more or less the same treatment as in the town and area at large--considerably better than America as a whole, but still sometimes upsetting, which is why I don't much talk about it.
