Any book that’s been banned is going to be freely available many places online, and if the government could actually ban things and have them disappear, piracy wouldn’t exist. I would look for queer literature on private trackers like MAM, and seed those files if you’re concerned. Although usually they have dozens or hundreds of seeders, so they’re not in any danger.
No matter what happens, in four years Trump will be gone, and queer literature will still remain. And piracy will be as strong as ever.
