OK, because I'm new, again, I don't know if this has been approached before.
Either way! Here goes...
Speciesism is the racism of the LBT world. And, it has been a subconsious theme running through most of the movies, if not all of them, most prominentley on the first.
Racism in the LBT world is now almost synonymous with the character of Topsy, which is pretty unfair. Certainly, he's a racist character, but he has become more tolerant with time. And considering Topsy's given a whole heck of hate, all the other speciesist/racist characters in the series are largely overlooked. I don't think that's fair.
Take Old One's herd for example: On the fourth film, they point-blank ignore every other species of dinosaur that has come to greet them except for their own, and make it very clear that only longnecks should be allowed to accompany them when they leave. It may not sound too bad, but if you think about it, if the Great Valley were to change as dramatically as the Land of Mists had, what would Old One have done with all the species of dinosaurs living their that weren't longnecks? I wouldn't put it past her to simply leave them to die. And being a segregated herd is not merely a by-product of being far-walkers, considering the mixed herd that arrived at the Great Valley at the beginning of the seventh film.
This goes completley without mentioning Ali's reaction. Unlike Cera's previous attitude to other species, it wasn't an aloof, snooty sort of thing, but it was actually genuine fear. Fear of what exactly? Fear of other species because of what she's been told about them? Fear of what her elders might do to her if they had learned she had been interacting with other species? Either one is possible, and if so, it is an almost Nazi-like stance.
Sure, Topsy's beliefs rubbed off on Cera, there's no doubt about that. But as far as we can infer, Topsy didn't force these beliefs on her, otherwise Cera would have been an extremely meek and mild character, very different from the head-strong threehorn we all know and some of us love. I'm sure that Cera adopted these beliefs because her father did, not because he brainwashed her.
So, anyway, give me your thoughts, not just on what I've said about Old One's herd, but about speciesism in general.
