Queer is a term that has been embraced and reclaimed by some of the MOGAI community as a symbol of pride, representing individuals who fall out of the gender and sexuality “norms”. Note: Not every MOGAI person likes or uses the term queer and you should never refer to someone as queer unless they specifically tell you that's what they want.
The pinks and blues next to each other represent same-gender attraction, the orange and green are for nb, and black and white for ace/aro/agender spectrum people as well!Flag source:
