Four years is a long time, especially after prevailing conservative media converged on transgender people as their punching bag du jour. Effective capture of the once-considered thoughtful, left-leading media landscape (see Washington Post, New York Times, The Atlantic, etc) and using it to flood the zone with biased, horseshit talking points does a lot to nudge public opinion.

Remember all those Iraqi WMDs that everyone said were totally there?

It's going to take time to turn people around, and the work is going to fall onto the backs of transgender people being oppressed and victimized until those media sources can no longer deny the inhumanity they facilitated.

Not that they'll apologize for it or anything.
