A few people already said similar, but plenty of social sciences have already done all that work of defining gender so we shouldn't have to.
It's not that transphobes can't find the information, it's that they don't care to listen to it anyway because it doesn't validate their own hateful beliefs.
It'd also help if they stopped burning our studies, books, and science centers down then pretending it's a new idea to be a transgender person.
