i'm doing an Essay about why people should go out and buy comics, and one of my points is the diversity with the new Ms. Marvel, Ghost Rider, Blue Beetle, Cyborg, Bunker, Amadeus Cho (Especially since he is becoming the new hulk), and any others because the list is getting long.
Then that's going to be a terrible essay.... If your goal is to write about WHY people should read comics, then a group of rather pedestrian characters isn't the way to approach it.
Firstly, diversity is never a reason to do a thing: I mean you do get that a diverse range of people do drugs & then commit suicide right? If your argument is that diversity is a good reason to read comics, then it must also stand that it's a good reason to do drugs & then commit suicide.
Here's an idea for you: Instead of peddling the PC line, how about you write an ACTUAL essay about why people should ACTUALLY get in to comics.
Because I can pretty safely state you didn't wake up one morning, see a comic & went "wow, this is a diverse group of people in this image, this is a thing I MUST get into because diversity."
Instead write about why you ACTUALLY got in to comics & why you continue to read comics: The deep characterization, interesting story telling, the unique mix of visual & prose elements give the best of movie quality special effects & novel level story depth. The idea of superheroes as contemporary mythology, satiating one of mankinds oldest desires for a pantheon of living gods to tell stories about.
Dig a little deeper than just parroting the current pc line of rubbish.... Especially if your teacher was a fan of comics in the 70's through late 80's, because he or she will have lived through the eras of ACTUAL diversity in comics. Not the cookie cutter tumblr-ism pandering we are trying to pass off as diversification now. They will have lived through the era of comics when creators actually took creative risks by creating new characters rather than just gender race swapping a white male character & calling it diversity.
Actually you know what, that's an essay worthy topic: The difference between the creative revolution of the 1970's & the creative stagnation of our current paint by numbers in mainstream superhero comics.
