I know several people have addressed the vegan elements present in the latest Star Wars movie, so I'll start by noting the elements that might disturb vegans. I'll finish by explaining why this movie ends up making some very pro-vegan themed messages.
Elements in the movie that are possibly disturbing to a vegan:
1. Some characters are wearing clothing that clearly looks like leather (including Luke Skywalker).
2. Chewbacca is holding the fire roasted remains of an animal called a Porg. It looks much like a roasted chicken corpse.
3. Luke Skywalker milks a creature called the Thala-Siren and then drinks it.
4. Luke Skywalker stabs a fish and carries the body on his back.
5. Several fish are seen dangling from hooks.
Now, clearly there are still many vegan themes in this movie. A group of animals called the Fathiers are being abused for use as racing animals. These animals are liberated by the rebels in the movie. And the movie addresses that these animals were being abused in order to get them to race. This is clearly a nod to animal rights.
In the scene where Chewbacca is about to eat the Porg, a sad looking Porg convinces Chewbacca not to eat the body. Instead he throws it away and embraces that Porgs are friends not food by allowing them to join him on the Millennium Falcon. This is another very clear animal rights message.
But, even when Luke is seen milking the Thala-Siren, it is made to look disgusting and happens during a time when Luke is clearly in some dark place. Good is clearly not raging through him. And then Rey, who is played by a vegan actress, clearly looks disturbed by Luke's behavior.
Shortly after this, Luke is seen stabbing a fish. At the exact moment that he does this a lightning bolt strikes and the weather turns rainy and gloomy as if signaling something evil had just happened.
In a movie full of obvious symbolism, even the non-vegan seeming moments seem to have vegan undertones to them. Maybe I'm reading more into things that I should, but nothing about this movie seems to give abusing animals a free pass. So, while some of the elements of the movie are visually or thematically disturbing to vegan sensibilities, the overall message seems to me very pro-vegan.
