If Janeway came out and admitted to being a Lesbian, I wouldn't have been the least bit surprised. Looking back, perhaps, VOYAGER's captain should've been the first homosexual character and I think it would've worked, probably ... it certainly would've elevated VOYAGER's status in the franchise legacy!
Jadzia and Mirror Mirror Kira don't count?
Plus IMO, making Janeway a Lesbian implies women can't be in a position of power unless she's butch like a man.
I think Janeway was fine as she was cause she was authoritative while holding onto her femininity.
I think its why the character was a great role model.
