My point is, comparing yourself to the kinds of people you'll deal with, you'll be welcome with open arms lol. Just do your job and you'll be fine! Also you'll be in a STEM field so your peers will believe in things like biology, chemistry, physics, math and supportive of your choices and who you are! People in medicine tend to be open. I know medical professionals who do tarot and other religions outside of work. I know some who've seen exorcisms and more!
I would guess that if you work in a medium sized or large city, you'd probably find more support. However, some things you can't control. Just be the best medical professional you can, learn as much as you can about your profession and the rest will take care of itself.
In addition to the healthcare company that I work for, I also volunteer with my local public health department which is very accepting of non-binary providers.
I think Craig gave a very good answer especially as a member of the medical field. I 100% understand your concerns for safety as I am the proud mother of three trans children. Two of which are getting ready to go off to college. We feel they will be safer in more urban areas where there is more diversity. But sadly no matter where you are there is always the chance of getting some ignorance, and or hostility. If you do experience this then be professional and take good care of your patient and who knows maybe they will think differently about non-binary people in the future. I am uncertain about Georgia but in California we are starting to have more gender affirming health care centers. So you could even go into a specialty area that possibly may feel safer for you. Hope that helps! Best of luck to you in your future!
