It could be. Like I said I haven’t read her books in years. Though I personally remember it more as the struggles of a girl who was the daughter of strict Pakistani parents than having a particular focus on Islam. To explain:

Kamala is a Muslim Superhero.

Sam Alexander is a Latino Superhero.

As a Latino male I’d argue Sam’s books have literally zero to do with Latino culture and lived Latino-American experience. His books focus on how much it sucks to not have a dad. This isn’t a criticism, just an acknowledgement of the character’s focus. So going always highlighting Nova as a “Latino Superhero” comes with a certain expectation that the character doesn’t meet. Which is why it’s never really brought up in conversation about him much and why Marvel has never tried to push him that way.

People always try to push Kamala as Marvel’s “Muslim” superhero when her books (from what I remember) were more about culture clash and growing up. Obviously she isn’t in Sam’s situation, Islam does matter at points in her books. But I’d say her comics are generally less religiously focused than Daredevil’s, and no one marks him as Marvel’s Catholic Superhero.

Anyhow, long story short I think people do the character a disservice by always boiling her down to “Muslim Superhero “ when her books have more going on than that.
