The reason the flag is in the Rust discord logo isn't because people are throwing their sexuality in your face. They put that flag up as a signal that the community is safe for other like-minded people. The flag stays up because the people who built the community want it up and keep it up. So the logo isn't juxtaposed with the LGBTQ flag -- juxtaposition implies contrast. Rust is intrinsically LGBTQ because it's built by LGBTQ people. That's the essence of community and languages if anything are communities.
This is what happens when someone's mere existence in public life is considered dangerous or "your sexuality being shoved in our faces" -- they stay inside, they find community in secret places where few people go, and they put up signs to signal to others similarly situated that they are welcome.
So of course we're not gonna take the flag down, it's up for a reason! Won't come down until that reason it's up goes away.
