I feel like someone who is "actively transphobic," meaning they are invested in not accepting trans folk, won't be persuaded. No presentation of facts or logic will, it takes time and some way to open their minds.
But there are a lot of people out there who believe some of those things to be true, and have a sort of default, passive transphobia. Articles like this can help them see that we, the transgender community, as well as medical and mental health professionals have thought and studied these issues and the trans experience a lot, and we really do understand a lot about what it means. It's not just some casual whim. Those people can be helped.
It will also help people who are supportive understand what we really are going through. Even if we could tell them a lot of those things, it's nice to have someone else make the list, and sometimes it's more convincing to have an abstract voice of authority than hearing someone we know. Especially if it hasn't yet been grasped that transgender people are every bit as sane as anyone else.
