Saw this on Twitter.
So the guy identifies as being a transwoman, fine. Does that need to be on the missing posters? If the person walked past me in the street, I'd just think of them as a guy. Being a transwoman doesn't change anything, and if someone saw Varhola right after seeing the poster, whether or not they are trans would come into it.
On the other hand, some of the twitter comments say JV ran away from home, rather than simply having gone missing. Maybe JV ran away to start transitioning, so if you see someone who looks like a guy in makeup and a wig it might help them to identify JV.
