To understand the contours of the renewed culture wars over sex education, sexual orientation and gender identity, start with a Rorschach test.
According to Gallup, the share of younger Americans who identify as lesbian, gay, bisexual or transgender has risen precipitously in the last decade.
Almost twenty-one percent of Generation Z — meaning, for the purposes of the survey, young adults born between 1997 and 2003 — identifies as L.G.B.T., as against about 10 percent of the millennial generation, just over 4 percent of my own Generation X and less than 3 percent of baby boomers.
Comparing the Generation Z to the baby boom generation, the percentage of people identifying as transgender, in particular, has risen twentyfold.
