"Being trans isn't a personality trait, it's just a human aspect."
I believe it to be a mental illness, this is why I called it a personality trait.
"Even if they're only a half a percent of a given place's population, they still exist everywhere".
There are also people who were struck by a lightning several times. Several times, Carl! But as people become of rare type and events become more improbable the whole story becomes less realistic (even if it DID or COULD happen in the real life. For example, it's totally possible to win lottery seven times in row without being a fraudster or buying all tickets. But it's very improbable). Don't get me wrong, I'm OK with unrealistic story if lack of realism leads to more interesting story (like story about a person who cries with tears of gold, for example), but it's not the case here. In "Beyond Yesterday's Grasp" I expected to get slice of life with a hero trying to overcome ghosts of the past. Instead I got story with REAL ghosts.
