I feel like by 2017 if someone hasn't become aware of trans issues it's because they're deliberately staying ignorant. I mean, this stuff is all over the news. Transgender people are constantly getting murdered and beaten, and people are even trying to prevent them from peeing in public bathrooms all the time.
There are so many good resources about trans people online, and i expect a bunch of Smart and Rational and Educated people (like HN commenters collectively think they are) to actually fucking educate themselves.
