A pride flag is any flag that represents a segment or part of the LGBT community. Pride in this case refers to the notion of LGBT pride. The terms LGBT flag and queer flag are often used interchangeably. [81]

In 1970, graphic designer Tom Doerr selected the lower-case Greek letter lambda (λ) to be the symbol of the New York chapter of the Gay Activists Alliance. [5] [6] The alliance's literature states that Doerr chose the symbol specifically for its denotative meaning in the context of chemistry and physics: "a complete exchange of energy–that moment or span of time witness to absolute activity". [5] On July 20, 2021, President Alberto Fernández signed Decreto 476/2021, mandating that the National Registry of Persons (RENAPER) allow a third gender option on all national identity cards and passports, marked as "X". The measure also applies to non-citizen permanent residents who possess Argentine identity cards. [133] The 2022 national census, carried out less than a year after the resolution was implemented, counted 8,293 (roughly 0.12%) of the country's population identifying with the "X / other" gender marker.

Alice Fisher of The Guardian wrote in 2017, "The unicorn has also done its bit for the LGBT community in the last century... Rainbows and unicorns are so intrinsically linked (the association is also a Victorian invention) that it's unsurprising that the magic creature started to appear on T-shirts and banners at Gay Pride around the world, with slogans such as 'Gender is Imaginary' or 'Totally Straight' emblazoned under sparkling rainbow unicorns." [40] The female and male gender symbols are derived from the astronomical symbols for the planets Venus and Mars respectively. Following Linnaeus, biologists use the planetary symbol for Venus to represent the female sex, and the planetary symbol for Mars to represent the male sex.a b c Tobia, Jacob (November 7, 2018).
