I see a fascist subtext in Marvel stories for some time now, and I believe it bleeds into readers.

The list of "smartest characters in the Marvel universe" is lead by 3 characters in particular (Reed Richards, Victor Von Doom, and Valeria Richards), and all 3 of them have shown fascist tendencies since 2010. Mr. Fantastic trusted his daughter's education (which includes political education) and care to a fascist dictator, Dr. Doom is the fascist dictator we are talking about, and Valeria Richards looks up to a fascist dictator and spends her time in dictatorships whenever she can, and becomes a fascist leader herself in some futures. The stories have plotted a clear link between "intelligence" and "fascist tendencies".

You can also see that when looking at the story of Wakanda. For many years, Wakanda's story was that it was a hidden, untouched African country brought to greatness in recent years thanks to the liberal, scientific mind of its young leader, T'Challa. In 2005, Wakanda's lore was significantly changed. It became a country that enjoyed thousands of years of Utopia under a traditional, isolated rulership, and the young leader T'Challa now has to deal with the constant turmoil caused by his liberal tendencies.

The fascist dictatorship of Latveria, in contrast, is portrayed as Paradise on Earth. One storyline in particular, "Doomwar", basically spells that the only Earths that "succeed" in making life good in the entire multiverse are the ones under fascism.

The link between "intelligence" and "fascist tendencies" can also be seen in Nadia Pym, the new Wasp. Nadia, a character created to introduce young readers to STEM, has a fascist ruler as her biggest idol, which might not be appropriated to the children that are the target audience of her books.

Not by coincidence, it is incredibly common to see comic book fans speaking positively of fascism. A large part of the community believes Dr. Doom to be a heroic figure, and the extra-judicial executions of the Punisher are lauded as a superior way to deal with criminals than the basic arrest done by mainstream heroes. It's inevitable, given the material they have been consuming during all those years.
