Why not? It's a handful of people. Only three of them are important to the story, who the rest are literally doesn't matter. And we'd already seen multiple men in the organization. There is no reason whatsoever to read anything into it at all.
Well apparently there is because Chabon has said that Romulan society is matriarchal. So that's probably the reason the scene was depicted that way.
It's easy to convince (some) christians to be crusaders. They already live in a world where 'God' is fundamentally beyond question. The only stumbling block is convincing them that crusading is God's will. As you said, this is an alien prophecy, not a native religion. So no, you can't just tell people second-hand and expect them to believe you. You have to show them the proof.
And what is this proof? It's a vision supposedly from some other alien civilization that they themselves never heard of or knew. How do they know they didn't stumble across some really potent space LSD?
And again, if they need this convincing to follow this path, how did they get recruits in the first place? As I said, they're already willing to sacrifice their own lives just to endure this vision. Seems like they already are true believers.
As for Oh, for all we know she's the first person in the Zhat Vash to ever have that capability so it would've been a tactic unavailable until now. And we don't know whether it really gives the full power of the vision or not, which would obviously be important to fanatics like the Zhat Vash.
If she's the first person to have that capability, because of her Vulcan mind meld powers, why didn't she do that for her sisters? It made for a cool, violent horror scene. Why would they need the full power of the vision to create fanatics. They already have people willingly join the Zhat Vash.
Jurati seemed pretty convinced without getting the full power of the vision, enough to kill Maddox. She didn't go through with it probably because she's not Romulan, not part of the Zhat Vash, loves synths, has a girl crush on Soji, and is friends with Picard's crew.
If you already dedicate your life to the Zhat Vash and are a Romulan nationalist, the half powered vision seems like it'd be enough to seal the deal.
There is also the question of the typical traditionalist nature of extremist organizations, as well - highly probable that earlier generations of the Zhat Vash might not trust any new agents who didn't experience the full, traditional initiation.
Do extremist organizations typically want to keep their groups that small by recruiting people who will go mad? What if these useless nut jobs blab about the Zhat Vash or their mission? What if one of them snapped and killed Commodore Oh and then herself?
You say that like we have definitive proof no one has ever dissented. We've seen less than half a dozen individuals. The ones who dissented presumably left the group. As Jurati is doing now. (Those stories Laris and Zhaban heard had to come from somewhere.) Or were probably killed, in some cases. This isn't really a hard thing to figure out.
No, but it's hard to believe that this group has survived this long without ANYONE in the Federation knowing about it, but apparently the secret that drives you mad about synthetics is somehow passed along by drunken Tal Shiar.
If there were dissenters that left the group, they didn't tell anyone about it?
Not just old Trek. Pretty much almost all stories everywhere (that involve multiple deaths, anyway).
So indulging in cliche. I have a problem with how action and death are portrayed in most mainstream action-adventure shows/movies.
They were representative of everything that had been done to all the ex-Borg. I don't have to know their individual names anymore than I have to know the individual victims' names from the Holocaust.
We're talking about fiction not real-life history. Not putting a name or story to victims is a sure way to help desensitize people to violence, which is why law enforcement or FBI have recommended to the news media to give a greater focus on the individual victims of mass shootings and less time to the shooter.
Just seeing a # doesn't carry the same weight as putting a name to someone, finding out who they were, etc.
Seven mourned for them, her people, openly and that gave them meaning - far more meaning than the named redshirts who died only for Captain Kirk to end the episode casually joking around with Spock and McCoy like nothing had happened.
The way people get killed in PIC lends some validity to the criticisms of its depiction of violence. Elnor is depicted as a very sensitive individual, even hugging Seven when she arrived. Yet he has no problem decapitating people right after uttering his obligatory catchphrase, "Please friends, choose to live."
Captain Kirk casually joking around like nobody got killed? That's worthy of criticism as well, so I don't know how it counters my criticism.
