I love Star Trek, always have, always will, and not afraid to admit it.
Unfortunately, there are a lot of folks out there, who have more than a little trouble distinguishing the borderline that defines reality.
You see this with other Sci-Fi venues, like B5 and Farscape.
Outside the Sci-Fi genre, there are groups who dress up in medieval garb, and act out battles with swords and armor, Civil War re-enactors, etc.
I don’t mean to disparage all those people, but I do think they tend to attract a minority of poor souls who need some serious help.

The real issue here is not the mental condition of the patients, but the insanity of political correctness.
