I think we're reaching a critical mass of visibility. There will be a bad reaction followed by eventual acceptance by society. The players are always the same. A new, marginalized group becomes visible. The average person, distanced, gives them no thought. Eventually they stick their necks out. While they're still a novelty most people don't give them a thought. Some prominent people admit to being part of the group. The vast majority are intrigued and titillated. Suddenly, they begin to realize that these people are their sons and daughters, their neighbors. A face is placed on the anonymous group. Some people, going by previous familiarity with individuals in the group, become various levels of ally. Some realize they were part of the group all along. Some people, equating newness and unfamiliarity with evil, are frightened, disgusted. When those people feel threatened enough something bad happens. Before long the entire population is polarized. Over some period of time, years, decades, centuries, the new group becomes part of the background and the reactionaries begin to lose their fear, if not their disgust. A new equilibrium is reached.
Our gay brothers and sisters are deep into this last stage. We're just entering it. No telling how long it will last though. Caitlyn Jenner is a symptom, not necessarily an active agent of change. She doesn't have to do anything other than be to move the process along and neither do we. The reactionaries are trying, intentionally or no, to push us back into the closet. Going in and shutting the door can only delay the inevitable.
