Transsexuals are folks who, through hormones and surgery, have changed their sex. Al Kirsch, 3 February 2001
A person who has had medical operation(s) to become the other gender. Also, anyone who is going to have an operation of that nature, soon, and is taking the hormone pills in preperation. Andy Weir, 5 February 2001
The flag consists also of many stripes, like the Gay Pride flag, but alternating in rosy pink and light blue (standing for both sexes?) separated by thin white stripes. On the upper hoist, a twinned Venus and Mars symbol ("⚥") in pink (a "bluer" shade) and outlined in black. António Martins, 3 February 2001
The combined male and female symbol has been included into Unicode since version 4.1.0 and assigned the code point U+26A5. [1]
The flag was created in 1999 by Johnathan Andrew, aka "Captain John," a trans man from San Francisco, who presented it at his website (no longer online) "Adventures in Boyland," together with many other sexual orientation flags. [2,3] Actually, he presented two designs, the images of which (as well as those of all other flags) were not saved together with the page itself, but his description, [3] presented as being related to both flags (unlike all other flag images, each with a description of its own), reveals that on the other one, blue and pink colors were reversed; the symbol in canton was in lavender color. The variant with four pink and three blue stripes has outlived Andrew's site because it was presented on FOTW website, as well as a few other sites. [2,4] It is clear from Andrew's description, though, that the flag does not represent only transsexuals, but transgender persons in general. [3] Tomislav Todorović, 30 May 2023 Sources:
