1. I disagree they’re trying to have the kirin emulate a culture as opposed to referencing but will concede your point.
    
2. The comics used written english because english speakers need to be able to understand it, even when the show used fictional text. I understand your complaint but this is such a common artistic license I’d need an example of how they could convey the meaning of foreign text that wouldn’t obstruct the work.
    
3. Proof? We’ve never seen any lands beyond what’s adjacent to Equestria. And the books Zecora read were considered fiction even in Equestria until recently, that’s why they’re dismissive. The trade thing is a legit point, but handwaveable by assuming they never cared for each other beyond trade. The show ran on not mentioning characters, places or things until story relevant no matter if they logically should have come up sooner.

1. The show not “ponnified” or “americanizing” non-pony cultures, the kirin is a good example in this, that is more cosmopolitan with European, American and Asian features. Much of the ponish culture is European.
    
2. Everyone speaks English/ponish, but written language is something else - here the show has shown foreign and different written language for the ponies. The IDW comics have a problem that they most often do not show this. Andyprice could copy the Nko script for the schoolroom to show an African touch. Nko is very similar to ponish, and easily accessible on wikipedia.
    
3. Equestria is no less dangerous than other countries with few exceptions such as Everfree and the Badlands as there are monsters scattered all over the world, including the zebra lands. Here it seems that Whitley wants to make Equestria a mythical country where there is not much knowledge about the lore there, and thus ignore two important contradictions; firstly, the books that Zecora read - secondly, the trade between Equestria and Casabronco; the pirates do not go to sea if there are not many ships to plunder.
    
4. I feel IDW is not as concerned with world creation as the TV show had been, more aimed at a far more limited audience as English-speaking children in the interior of the United States. Then it meant that the whole idea of friendship expeditions to non-pony cultures and societies could be a boom shot if one is not as frivolous as Hasbro had been. I wonder what would have happened if Hasbro had allowed an expedition to the Zebra lands while the TV show was going on

1. When has the show been better about not Americanizing cultures? Most have no real world equivalent save the Buffalo and Yaks and how are they deeper than stereotypes?  
2. Everyone speaks english whatever it’s dubbed in ponish in the show. Zecora’s native language was made up because Lauren Faust admitted they didn’t have time to come up with authentic Swahili.  
3. Even the inhabitants of Equestria didn’t know those mythical characters were real, even those alive during their time. The claim Equestria is more dangerous could also be misconception, especially given how frequently it’s been endangered in the relatively short amount of time covered by the show?
    
   Your critiques are valid, but it’s an exaggeration to say the show was that much better about it.

@Incursor Because that angle worked out so great in Picard.
