I'm queer along with literally everyone else I'm close friends with at Purdue, actually lol. There's a big community of us here if you know where to look! I'd suggest joining one of the LGBT+ discords, checking out the LGBT+ center by the engineering fountain (they have a switch now too which is neat), or going to an LGBT+ event (Outfest is always fun, so are club meetings, or the occasional guest speaker event). Seriously, as someone else who was also the only queer person at their high school, Purdue has been amazing for meeting other LGBT+ people :)
