I have found tech jobs ( I'm a computer programmer ) far more oblivious to and accept of my male-to-female transgender status. This may be because they are fairly smart and socially liberal culturally, but also because they pretty much are obsessed with the technology. If I bring niceness and aesthetic pleasure to my presentation, interactions, and code, then that improves everyone's morale, but for a few. Many of the non-tech people appear uncomfortable often.
