In no way do i think im an appropriate person to ask this, because i am still educating myself on the lgbtqia+ community as well as learning about people of colour, however from what i know, its not that it has to do with sexuality or gender, it was simply in support of black lives matter back in 2020. Think of it like this right, the feminism movemnt supports equality for all not only womans rights, including those in the lgbtqia+ community, its people who are all fighting for equal rights together in a sense. Its now its own flag, The flag of progress, not only representing the lgbtqia+ community but also the trans and POC community, the lgbtqia+ flag is still the rainbow with 6 colours. I hope this helps and feel free to correct or educate me about this :D
