The colors are also common in ALL 2010s-era media. Vaporwave, Corporate Memphis, Mallsoft, Kaybug, the twisted necromancing of McBling, and absolutely in LGBTQIA+-whatever media, which isn't bad (the 2010s was an actual cultural decade) in general (especially not in reference towards that last one) but everyone was a sexuality civil rights protester in Hollywood in that decade and the general color scheme was so common that a 13-year old may be realizing for the first time that we once used red. We used green. We used yellow with red and green and blue, in so, so many ways.

Experience is relative. The 80s was never as pink as Vaporwave makes us think it was. The 70s was brown because of Kodak color cameras made specifically so that "Black" people's skin now shows up as it's actual color on film (and digital photos). The 60s was more than counter-culture. The 90s was indeed a golden age, but one that was built on foundations too unstable to last. The 2000s were not devoid of culture, but drained of it by the "War on Terror" and shallow celebrity cultist behavior.

Someday, people will look back on this like a news article from WWII. Elon's "Xitter" logo is the new swastika, mark my words. As for the American Flag, it'll be lucky if it gets off easy like the Soviet Flag did.

The colors are the trans support flag. Trans people make up about 1% of the population.

Whom is the message directed at? People who would get those frames of reference?

Telling gender activists who would get those frames of reference that they are focusing on the wrong 1% would be odd. Telling the people focusing on the wrong 1% using frames of reference they would likely miss is odder still.

For lack of a better word, the message is a bit subculture-centric by assuming everyone shares a particular frame of reference. Of course, you understand, but that's preaching to the choir.

Unless you immediately get the frames of reference, it is hard to understand. That you think it isn't indicates a self-centered myopia.

Do they?
