Armungus is not a bad character because he is unmasculine,he is bad because the plot bends to make him look smart, such as Hansi who worked with titans her whole career needing to be told by Shartmong to do the mission at night(for fucks sake, she is the character that tells us this but only OINKmin can put 2 and 2 together). Or how Armin worked with Marco on his gear and autistically noticed every detail despite the characters never talking, and him being both next to Annie for inspection and Annie using Marco's gear instead of her own, all of these coincidences come together to make it seem like Armin is a genius when it's just convienent writing to wank Armongshart. Somehow Armong is the only one to think of using the big titan to cover the big hole with a big boulder, even though Pixis is a general and should be well aware of the circumstances of the city he commands. The first time Erwin ever interacts with Armin he gives him command over the operation for finding 3 cups and making the genius inference that there must be 3 people. He is the worst type of "intellectual" character because the most he does is make basic observations anyone could make, but only his is allowed to oink them.
