Re: So I'm supposed to believe alt-Kira, Ezri and Leeta are all lesbia
I don't think mirror Kira is a lesbian, I think she is a hyper-sexual narcissist who uses sex to control others and get what she wants.
She uses sex as a tool to gain and maintain power over those around her and likely doesn't feel any intimacy or pleasure related to it.
Since it means nothing to her, it doesn't matter if she is doing it with a male or female.
Bingo.
I think MU-Kira's same-sex activity in
Emperor was a mis-reading by the writers of her narcissicm in
Crossover, which was more about there being another Kira than another woman. But if there needs to be an explanation, then the above is it.
Besides which, it all fits with what's always been depicted about the MU anyway. Sex is used as currency, persuasion, punishment, stress relief, and only in very exceptional circumstances as actual intimacy or romance. Hell, when you've got Garak offering sexual favours to Worf in an attempt to improve his position, you can't put much stock in it one way or another.
Which is why I also have no problem with Ezri and Leeta being gay too. In that kind of culture, I imagine that the lines between what's "acceptable" sexual activity and what's not have long since dissolved. That leaves people open to looking for love wherever they can get it, since they're not culturally conditioned to only look for it in one place. That could explain MU-Leeta being willing to have sex and even enter a relationship with a woman, even if RU-Leeta wouldn't.
As for Ezri, well we already know Trills in general have a more fluid sexuality in the RU, so I imagine it would be even more so in the MU. When you live your life as both a man and a woman multiple times, again, sexual orientation lines tend to lose all meaning. And even though that only applies to the minority of joined Trills, surely that attitude would trickle down to the unjoined majority as well.
So I have no trouble with the idea that, while joined Ezri Dax (RU) is mostly oriented towards men thanks to the influence of the symbiont and the most recent past host and the location where she is (that is, still hanging around Worf and Bashir who she has history with, and note we never saw her express interest in any other man besides them), unjoined Ezri Tigan (MU) could well be genuinely lesbian (she gets married to Leeta in the Lit) but willing to do what's necessary to get by with both men and women (Kira, Brunt) when the situation requires it.
