For better or worse, as we're talking about less then 1% of the population... it's hard to picture a Network Show giving much prime time focus on a topic that effects such a small demographic (when they need to draw millions of viewers to break even). Although I would say that if a transsexual comes along who inspires folks, or has a great personal story then undoubtedly they will make appearances. So yeah, you're probably going to see Caitlyn Jenner from time to time.
I imagine you'll survive...
