Not sure and not queer here.

But my guess is, that the woman in the cis pic has very trimmed, slim eyebrows - while the others have more natural looking brows. Maybe because the queer folk don’t need to play the “stereotypical female game”. They are defining their own sense of femininity, so no need for conforming with patriarchal stereotypes?

Again, just my guess. If I’m wrong: please explain. I’m always willing to learn & evolve.
