German Lopez writes for Vox: “As LGBTQ and transgender issues drip into mainstream discussion, so too do views that go further to challenge America’s gender norms. It’s now more accepted if someone is a man and loves a man, or if someone is designated a woman at birth and identifies as a man later in life — or perhaps during childhood. Seeing this progress, others are trying to expand concepts of gender even further — to directions many Americans may not be used to.”
