Idea for a cartoon, all described events are fictional:

Texas passes a law that makes it a criminal offense to produce, distribute, sell or possess sexualized depictions of minors, cartoon or real, or drawn as art, or generated using AI, treating it as a first degree felony punishable by 1 to 5 years in prison. Sale, production and distribution are second degree felonies, punishable by 2 to 10 years in prison. "Sexualized depiction" does not follow the definition of obscenity, and is instead its own new thing defined as:

material or performance, that the average person, applying contemporary community standards, would find that taken as a whole appeals to the prurient interest in sex;

(So only the A of the official Texas obscenity definition, without the B and C)

In response, all otaku places in Texas rip off their anime girl posters from the walls and gather together to decide how to save their businesses. They devise a genius plan. They will commission artists to draw lolis with big boobs and only keep material that features bearded male and big boob female characters. Seeing a loli with balloon titties stunlocks karens and they can't compute the age. The thing grows immensely popular, unable to be stopped by police and courts, as in each case the cartoon subject is found to be above 18. It even spreads to non-otaku places, like normal restaurants, and into ads and, god forbid, even the last bastion of hope - the TV. Soon, the only female representation in media is fat, ugly women with giant tits. This causes flat chest female population to feel underrepresented and ostracized. They gather in protest, shadowing other movements like LGBTQ+ and gay parades, to stand up for small tits rights, saying things like:

Small boob power

No taxation without representation

...I need to take a break from watching censorship news.
