A study of millennials found that they readily see themselves as being on the gender spectrum, rather than binary.
20 Percent of Millennials Identify as LGBTQ
http://www.out.com/news-opinion/2017/3/30/20-percent-millennials-identify-lgbtqOnce I became aware that I'm a non-transitioning, nonbinary, panromantic, asexual, partial transmale (Whew! That's a lot of labels) I realized transgender people were already everywhere, but I hadn't noticed.
1. My favorite aunt, now diseased, was partnered with a transmale
2. My youngest sister and daughter both identifed as bi nonbinary after they stopped to think about it. My daughter now attends Native American ceremonies as a two spirit honorary shaman
3. My ex-husband came out last year as nonbinary female and is seeing a VA gender counselor for transitioning purposes.
4. I have been in Thailand since 2010 and it seems that being nonbinary and bisexual is the norm here.
