Jokes aside this suffers from the Disney villain trope where the villain is 90% correct but they have to shove in a 10% evil so they can be villains and you oppose them.
Shinzon was a Picard clone who was turned into a slave alongside Remans who are used as slave labor, and his plan was to free the Remans from servitude and it looks like he wants to (more than just free the Remans from servitude) annihilate the federation and Romulus. I completely admit I'm only about 60% into the movie so perhaps there's more at play but it certainly doesn't look that way.
Shinzon just seems to be evil for evil's sake. Even Picard, upon hearing that Shinzon fought to free himself and Remans asks 'how many Romulans died for that freedom?'; what absolute utter lib crap. Even Shinzon's answer, obviously not his true feeling on the matter (as at the time he was attempting to deceive Picard) was 'too many', as though the people enslaving you should be safeguarded when breaking your chains; there was nothing in the movie (at least up to Picard's chastising question, and perhaps for the entirety of the movie but again, I've only reached up to about 60% of the movie) that indicated that Shinzon had gone after civilian targets.
Didn't the federation literally fight off the Borg to maintain humanity's freedom? How many Borg died for that freedom? Absolute lib crap.
Then I go on to twitter to at least see some beautiful tweets about people like Paul Kagame of Rwanda who strove for national unity and reconciliation (https://x.com/shawnchauhan1/status/1874146691542376640); there are so many movements outside the West that seek to end persecution peacefully, but it is never depicted to us in our media that such horrific chapters could be ended peacefully, or that our victims aren't secretly aiming to wipe us all out, that peace is deeply desired by everyone. The fears that rolled over Southern slave owners when the people of Haiti revolted and broke their chains still feels alive today.
I disagree. A recurring theme in Star Trek is that life doesn't always follow the paradigm that humanity does, but is nevertheless worthy of respect. In the Trek verse we see that humanity has finally applied that logic to animals (in Riker's words ending animal enslavement), there are episodes where rocks develop intelligence and the solution to the problem is negotiating with them, and then there's the crystalline entity which - while it was ultimately destroyed in self defense - Picard tried to negotiate with as much as he could.
The crystalline entity was destroyed against the orders of captain Picard. IIRC they were learning how to protect themselves and attempting to communicate with it when it happened?
