Blaze, I get the feeling you're pretty young, as well as being new to writing, and those are both great, exciting things to be.
But I think it's important for you to realize that good writing is powerful. And, as you've probably heard, with power comes responsibility.
If you're just writing for yourself, write whatever you want, however you want to. But if you're writing something that you hope to show to other people, and maybe even get published, then you have the responsibility to think about the people who might read your work. It's admirable that you want to write something different and original, but remember that you need to responsible, as well. Whether it's this topic or any other, things are controversial because they're complicated. Trying for novelty is great, but you absolutely need to educate yourself and make sure you get a deep, true understanding of the topic.
So, this thread was a great idea, but I think you may be underestimating the challenge you're facing. In order to write about transgender issues effectively, you're going to need to know a lot about gender studies, sociology, psychology, medicine, law -- all kinds of stuff!
if you decide to go ahead with it, good luck, but don't feel as though you need to stick with this idea right now. You can always put it on the shelf for a few years and come back to give it another try when you're ready.
