They understand that the US does bad things, but have a black-and-white worldview that brings them to the conclusion that anyone who opposes the US must be heroes. They don't understand that both sides of a conflict can be shitty.
It's a semantics argument that's worked in the past, to some extent. Before the supreme court made same-sex marriage legal nationally, some states introduced "civil unions" as an alternative to marriage for same sex couples. They were often functionally identical to marriage, but since they weren't called marriages you could get some conservatives to approve them. Not enough to get them passed in red states, but enough to tip the balance in swing states.
There are sites that catalogue both scripts and transcripts. Should be easier to just download those than try to rip subtitles off of the DVD releases.
Can actually be done without any inbreeding. For instance, if a man has children with two women who are sisters, the children would be paternal half-siblings and maternal cousins. Used to be fairly common when arranged marriages and dying in childbirth were normal. Wife died, but the marriage ties are important so you marry her sister.
Shadow of Mordor and Shadow of War actually explore orcish culture and morality, the latter game more than the former. Ultimately, they've spent all their lives in a Morgoth and/or Sauron cult. The ones that don't buy into it are more chill, and some show signs that they could be decent or even heroic in different circumstances. Eltariel is able to make some progress deprogramming a couple, but siding with Talion, Celebrimbor, or even Eltariel mostly just has the orcs cast them as their new Dark Lord. It's probably possible to get the bulk of the orc population into a better place, but it would take many generations of concerted effort at a massive scale. They'd have to replace their entire belief system and most of their way of life just to leave the cult. Additionally, even when not following a Dark Lord, the orcs culturally favor bloodshed to settle conflicts. This isn't too big of a problem with other orcs since they can take shockingly large amounts of punishment without dying, but it's a huge problem when interacting with anyone else. And even that's probably solvable without wholesale destruction of orcish culture, but everything would take so damn long that it's well beyond the scope of LOTR.
While the 5090 will run the latest games great, it will struggle with many older games due to the RTX 50 series having dropped 32-bit PhysX support. RTX 40 series cards are nearly as powerful and have 32-bit PhysX, if backwards compatibility is a concern.
