It’s not all black and white
Saying that lgbt+ people didn’t exist before there were terms to describe them is such an odd concept to me. It would be like saying people with vision problems didn’t exist before glasses. People with vision problems have always existed, it was just a lot harder because they didn’t have ways of coping. They didn’t have glasses or a diagnosis.
The labels we’ve created for ourselves are not just new age, pandering made up terms. Gays and bisexuals and trans people have always existed. They just didn’t have a word for it.
