March 31 is the annual Trans Day of Visibility! Celebrating the existence of trans and non-binary persons everywhere, because they have so little representation in media that they're practically invisible to the larger population except as jokes.
Trans people are real people. Non-binary people are real people. They're not jokes.
If you're cis and you haven't yet taken the time to read about the experiences of trans and non-binary persons, followed their blogs, or even familiarize yourself with common terms, DO IT. You need to start looking at trans people as human beings and push out all those old messages from media that say they're nothing more than jokes and gags.
If you're on social media, find selfies of trans and non-binary individuals and share them. Make sure all your friends get to see some amazing trans faces.
