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.
