Like the title said. Plus the author (Mr. Hideaki Anno) even admitted Evangelion is Mecha/robot anime
Also Evangelion appeared in Super Robot Wars game many time before.
Eva uses mecha aesthetics, but it isn't about the mechas or the robot action, so it kinda isn't mecha. On the other hand, in technical terms it kinda is mecha, since it features giant humanoid robots.
Now, this comes to a question of how to define genre and what purpose does it serve. If genre is just a checklist of features that a work needs to fulfil, then Eva is mecha. However, if you use genres to group together works that will likely appeal to similar people, Eva isn't mecha. It doesn't share the focus on mecha action that may appeal to Gundam fans, or the usage of battle tactics that may appeal to people who loved Code Geass.
In the end, the reason I'd say Eva isn't mecha is to differentiate it from stuff like Gundam, especially since even people who don't like mecha can like Eva.

The author need not have the final word when it comes to their work.
It can be debated how much authorial intent even matters, but regardless, Anno saying that Eva is mecha doesn't change which elements the series has, and which ones it focuses on.
Eva isn't the only philosophical or thought provoking mecha anime, nor is it one that involves a younger cast while still having those ideas. Patlabor is thought provoking, so is Ideon. Hell, Gundam is. And while we're at it Eva's action ratio compared to the original Gundam isn't even that diffferent. I don't commit it all to memory but a good half or more of Eva's episodes have mecha battles. Less than Gundam on average but not substantially so. Turn A Gundam would also come close to that number which is literally a Gundam series that epitomises mecha anime.
Patlabor also has little emphasis on mecha action compared to usual, it doesn't mean it isn't mecha. Macross is one of the biggest mecha franchises and yet the action in the original series is almost secondary to the romance plot. Mecha is a term you use to describe a show that involves giant mostly pilotable robots that are usually but not always humanoid, it doesn't matter what the topic is or how often they're utilised. A mecha anime can be anything it just happens to usually have narratives that can crossover with other mecha shows very often. The mecha "genre" is a massive misinterpretation, it's a category that can have many different genres accompanying it like a shounen can be slice of life or action oriented. 86 is also a show that people would say isn't mecha, but it is. The main method of battles involves the use of giant pilotable robots with the only differentiation being that they aren't humanoid. It's strange that people can not see this when there's such a discernable difference between a show that uses robots in battles and a show that doesn't even when the battling isn't the main part of the show.
Not every show has to have a unique blanket phrase to appease a fraction of people that don't want to believe what is true. Eva and 86 are mecha just as Gundam and Gurren Lagann are, it's just a term. Yes some people only like Eva and no other mecha shows, that's just down to personal preference. You could easily find someone that hates sport manga/anime but gives Slam Dunk or Haikyuu a pass, because they're good ass stories. That's how some people perceive Eva.
The mecha "genre" is a massive misinterpretation, it's a category that can have many different genres accompanying it
Completely agree. Mecha is more of an aesthetic than a genre. A genre should reveal core elements of the narrative like action, romance, or mystery, and mecha only means that the show has giant robots.
If we consider mecha as a set of aesthetic elements (same as fantasy or sci-fi), Eva is definitely mecha.
The main reason I usually don't call it mecha is for clarity, since most people have a defined view of what mecha is, and Eva mostly doesn't fit that.
86 is also a show that people would say isn't mecha
Really? Tbh I've never seen anyone saying it's not mecha. But I haven't been paying attention to most of the discussion surrounding it.
i think the 2 main reasons why are:
I mean, by all technicalities
they're technically kaiju with armor
Technicalities aside, anime fans can be ridiculously pedantic, especially, in my experience, the ones that tend to be the die-hard Eva fans.
I think it does belong in the genre, mainly because the specific subgenre it technically should fall under... doesn't really exist outside of Eva.
