2015: In December, Washington State had clarified that existing law allowed transgender people to use bathrooms consistent with their gender identity.
In September Philadelphia adopted rules that would require gender-neutral signage on single-occupancy bathrooms. “It’s a sign change,” said the mayor’s director of LGBT affairs. “We’re labeling restrooms as what they are: restrooms, not gender-monitored spaces.”
In July the Justice Department took the side of Gavin Grimm, a Virginia high-school student who argued that he should be allowed to use school bathrooms that match his gender identity.
In April President Obama opened the first gender-neutral bathroom in the White House.
These actions were largely a response to transphobic laws that had been proposed in red states all over the country:
Late 2014 and early 2015: Texas and several other states introduce “bathroom surveillance” bills that would require transgender people to use bathrooms that match their birth gender. The communications director at the National Center for Transgender Equality says the wave of new legislation seemed to be a backlash to “the gains we have seen in state and local non-discrimination policies that protect transgender people.”
For example:
August 2014: Austin approves a law that requires gender-neutral signage on single-occupancy bathrooms. Among others, they join Portland (one of the first a year earlier) and Washington DC, and are soon joined by West Hollywood, Philadelphia, and San Francisco.
These cities were largely inspired by:
2012-13: A growing movement to install gender-neutral bathrooms at university campuses. During this period, 150 university campuses installed gender-neutral bathrooms, along with a
growing number of high schools. The movement for gender-inclusive bathrooms in public facilities started
at least as early as 2009 in the state of Vermont.
Ancient history: For our purposes this is anything more than five or six years old. A few random examples include
Toilet: Public Restrooms and the Politics of Sharing, a 2010 collection of papers about (among other things) nongendered bathrooms.
In 2005, U of Chicago law professor Mary Anne Case gave a presentation called “On Not Having the Opportunity to Introduce Myself to John Kerry in the Men’s Room.” She has been performing surveys of men’s and women’s bathroom facilities for years. And of course, there’s the ur-hysteria of recent decades, when Phyllis Schlafly led a campaign against the Equal Right Amendment throughout the 70s out of fear that it would lead to gay marriage, women in combat, taxpayer-funded abortions, and, of course, unisex bathrooms. We never got the ERA, but as it turned out, Schlafly was pretty much right, wasn’t she?
