Treating other people/animals as inferior because they don't speak "English" has been such a historically common theme that it's surprising you seem to deny it.
Nations bent on conquest and colonialism had been using those arguments to justify their actions for centuries. Not to animals but to other humans as well.
While it's mostly illegal to do so to humans now, it's still socially acceptable to do the same to animals.
We still don't know how human intelligence developed or the evolutionary pressures underlying our intelligence. Using that as an argument to summarily dismiss animal intelligence is a strawman at best, as is your other points - you could easily find humans which are literally dumb as a rock, does that have any bearing on the intelligence we're capable of as a species?
I'm not denying that people never treat other people as inferior because they don't speak English. I'm saying the reason people treat hamsters as inferior isn't "because hamsters don't speak English", and that saying that is as uninterestingly dismissive as saying "it's because hamsters don't wear makeup".

No it isn't. If cows have no reason to think thoughts to survive, do not compete with tricksy, planning, vicious cow-enemies on evolutionary timescale, display no visible deep thinking behaviour, cannot visibly communicate deep thoughts to other cows, to say "but they must have them because reasons" is not good logic. Me asking "why star a-priori with 'they must have them?'" is not a strawman or a summary dismissal.

Your position is that "Some humans are stupid so cows are smart?" Really? Where's the cow Einstein, the hamster Beethoven, the Kangaroo Gandhi, where's the wolf whose face launched a thousand ships, or the beaver who added hydroelectric lighting to their damn? The intelligence humans are capable of as a species has taken over the world, it's bloody obvious, you can't miss it for looking - tool use, machine building, theorem proving, organising on a large scale, on a timescale which outlasts one lifetime while adapting to changing environments on a scale of hours to months not hundreds of lifetimes.
The presence of dumb humans doesn't undo that. The absence of all that surely does call into question the intelligence bears are capable of as a species.
I don't really know how you fail to comprehend this -- people have been proven to underestimate or look down upon other people who don't share the same language or looks. Whether it be barbarians, people with different skin color, or generally of different cultures.
And you just reply with "it's OBVIOUS that animals don't possess the same level of intelligence, show me the cow Einstein". The GGGP's point is that studies on animal intelligence is only surprising with this attitude. I feel like you're just trying to appeal to common sense without actually addressing people's point. Don't forget who made the claim that '"As if they are inferior because they don't speak English" is a pretty cheap shot'.
I'll sign off here. You are free to presume that we're unreasonable idiots who don't even have a speck of your "common sense".
The cow also does not write equations, does not do media interviews, does not drive a motorcar, does not write letters to the cow government on the dangers of atomic warfare. The hamster does not play music, gather other hamsters around and share music, does not make musical instruments. The kangaroo does not rally the crowds for the salt marches. You don't need to speak German to hear Beethoven's music, speak Gujarati to see Gandhi's rally, or speak anything to obeserve humans solve problems on massive scales which no other animals do. It's not that the hamster doesn't write /musical notation/ it's that the hamster /doesn't make music for orchestras/ to note in any notation.
The disconnected lever fallacy is the idea that you can take the lever from a ship's bridge to your home, and then when you move the lever, expect your home to move like the ship moves. Without knowing about the engine. You're taking that idea even further - without ever seeing the ship move, and having no lever for moving it, assuming that there must be an engine but it's hidden by the lack of a lever. It's not the absence of lever which is so important, it's the absence of powered movement.

I'm not willing to assume that hamsters must, a-priori, be capable of the works of Beethoven because you think it's racist not to. English speaking humans are racist to Spanish speaking humans. That's /not the same/. You don't need to speak Spanish to observe that Mexico City is many orders of magnitude more than what hamsters can demonstrably do.
(I also take this the other way; seeing that animals show emotional behaviours and therefore have emotions. I don't think animals are rocks, it takes some intelligence to find food, mates, build nests. But that's not demonstrating high or human level intelligence because humans are capable of so much more. I think it equally bad that humans do/did surgery on human infants without anaesthesia arguing that they "don't feel pain" ( https://www.bostonglobe.com/ideas/2017/07/28/when-babies-fel... ) and ( https://www.google.com/search?q=open+heart+surgery+infant+no... ))
