I agree with Suzi. The best thing those of us who are willing can do is to be out there and visible, regardless of our stage in transition. I'm entirely out at work despite my job making it difficult or impossible to wear makeup and our clothing options being unisex. On vacation I did outreach. I spent the whole day at EPCOT in shorts, sneakers and a red sports bra. On the cruise I was just as out (except in foreign ports, not ready to risk that in Mexico or the islands yet.)
People like Janet Mock, like Caitlyn Jenner, are important to our acceptance, but they're singular, they can be dismissed as rare and not an example of reality by people who would rather we didn't exist. Trans people, visible everyday, will be what gets us accepted.
Perhaps it's a dangerous path,but a necessary one.
