Here is the list again, and it is a list that includes those who she suspects to be BISEXUAL as well.
Picard? His sexuality has been debated on this site before. She is not the first one to suggest old baldy could be bi.
Bashir? Again, his sexuallity has been debated before. She isn't the first.
Garak? Well...he does have that gay vibe, and Robinson him self has touched on it.
7/9. Again, her sexuality has been discussed (even fantasized) about.
Dukat? Not sure about that one. I get no 'vibe' there. How she does? I don't know. I'll have our gay friends, who are not TREK fans, watch and get back to you.
T'pol. Same as 7/9.
Alexander? mmmmm...I can see this one.
Wesley. Again, this has often been debated on this site...so she isn't the first.
Jake. I don't see it.
Q? Oh definately. He even states he should have appeared as a woman. That alone puts him on the 'bi' side of the vibe. He plays Q about as trampy as Depp's Captain jack. And he has a bi vibe too..
Beverly. She leaves the possibility open in her Trill moment, or so some have said...I agree
Troi? Same as 7/9 and T'pol.
Sorry kate, but I think the more I read my wife's list? I think she was only absolutely wrong with Dukat and Jake. Thats not a bad record, and certainly better than 50%
Rob..
But Rob, I don't understand...You seem to be saying that your wife is "right" because other people have speculated the same thing. But what does that have to do with anything? Do you think that the fact that some people have said A and others have said B automatically validates A and B?
Because it doesn't. It neither validates them nor invalidates them. As you know, people speculate about all kinds of stuff, and so the fact that some have debated this character or that one proves only one thing: There are people who enjoy speculating about this character or that one.
You see what I mean? I think you're saying that "Other people have thought the same thing!" proves something. But it doesn't - not in and of itself. I'll grant you that if most people have thought the same thing, or a significant number (and how you define that, I have no idea), you might be on to something. But that there has been speculation proves nothing except that people (except for me, apparently

For what it's worth, I agree with some of them, too - Q, for example (although I'd say he is neither gay nor straight nor bisexual but is instead able to assume whatever sexuality, including none at all, that fits his purpose at any given moment - I mean, he can do and be whatever he wants, right? and why should he consider himself tied down to human/mortal/carbon-based lifeform standards of sexuality since he's none of those things?), and quite possibly Garak.
The old saying is, "There's no smoke without fire." Well, when it comes to this sort of speculation, you can actually have a lot of smoke and zero fire. People just like to speculate about these things, and so long as they are doing it in a lighthearted and nonjudgmental way about fictional characters, as you and your wife do, it probably doesn't do any harm. But don't take "Other people have thought the same thing!" as proof of anything except that other people have thought the same thing.
