1) Pretty women can indeed be otaku but not in obsessive way most likely simply due to the fact that they are popular (while male counterparts aren't as much even if they handsome). And in general men are more laser focused i.e. obsessiveness can be over the top which means and activity can get ugly.
2) I don't want to say anything about magical unicorns (i.e. FMC) simply due to the fact that i didn't see much of them in comic conventions. (Most were not otakus but normal girls with INTEREST in some anime/manga/comics).
3) Jealous from insane escapism that promotes further degeneration of society or at least proves it?
My point is even escapism must have some sort of scale where it is going to far. In recent years (10+ years) trend of creating an ultimate escapism to people with 0 character and "good" guy vibes is over the top. Too much content that promotes it.
If you want a beauty you also have to have something, because there loads of men aiming for the beauty.
These 0 character "good" guys should face the reality of things. They are mostly "good" (in their minds) because they can't display strength or power, sadly weak people don't have the privilege to show how good they are (rare cases of true self sacrifice only).
What i've seen though is some "good" guys becoming arrogant pricks when they acquire good jobs, riches or something to hold over other people. They were "good" as a show of not being a threat to those who could fuck them up right until they had more power to fuck someone up.
Jealousy(envy) is mostly derived from delusions. You think you must have it or you earned it but someone else has gotten "it". While i do indeed display envy for I am a human but unlike an animal i have mental capacity to improve and/or change consciously.
Whenever i feel envy, i analyze it and most of the times it goes away because my envy was misplaced.
Lastly envy goes away with age for the most people, it mostly ascribed to not having what others have because you yourself have too much free time and are doing something you don't like. When you become older most of the time you find things you like and occupy yourself with them thus looking at someone else becomes less frequent.
P.S. I'm here because it's my hobby, i read and i sometimes write my opinion. I have also my personal beef with manga industry that is degenerating since i've been a fan for over 20+ years and i see a clear downward spiral in bulk of anime/manga. I know Japanese current problems to some extent and i'm amazed that they cater to problematic character types instead of trying to correct them. If before it was blessings came from the heaven but i'm still gonna try push some weight too, now it is blessings came from the heaven and i'm going to just float along the waves.
