In fact, we need to think about sex and gender in a more ecological kind of framework, understanding that changes in one environment inevitable impact changes in other environments. Gender here might be thought of more as a climate or ecosystem and less as an identity or discrete bodily location. And so when we see sex/gender events like the pregnant man, like heteroflexibility, like metrosexuality, like gender fluidity, we are witnessing the aftershocks of the massive shifts that the emergence of transgenderism announced, presaged, and caused. Future shocks are on the horizon, and instead of trying to prevent more damage, we should be hoping that one particularly powerful tremor might bring the whole crumbling edifice of normative sex and gender crumbling down.
