The GayBeeCee's Crossword

What do all those letters stand for? Here's a rainbow explanation. 

LGBT, GLBT, LGBTQ+, LGBTQ2SIA, there's a lot of different official and unofficial initialism used for and by the LGBTQ+ communities that has been evolving since the 1990's when LGB was used to replace 'gay' in reference to the LGBTQ+ community in the 1980's. As our understanding grows of the wide diversity and variety of the sexuality and gender identities of humanity, so grows the number of initials. The design is shaped like a crossword like format, as a way of showing how intermingled and connected these things are, coloured with a rainbow because it's beautiful.
