This is exactly the reason, it became a meme (like Fallout New Vegas becoming a thing in the trans community before it) and people ran with it. People have retroactively said that it's because blåhaj is trans pride colors but it wasn't the initial reason.
How did Ikea's Blajah became the symbol of the trans community ?
I feel stupid for asking, but how did the trans community decided that the giant shark Blajah will become their favourite plushie ?...
