Hi Kerri,
Sounds like a good paper. What about India as your second country. Bound to earn you extra points, perhaps a HD. The caste (Think that's the correct spelling) section of society can in some ways be quite complex, yet so highly organised and regimented and legislated to a degree, from what I understand.
For my 2 cents worth, With respects to explaining transgender terms, keep it simple, you may be preaching to the non converted, and you don't want to confuse them up front. Otherwise they may lose the rest of your paper.
Let us know how it goes, and if you need more help.
Be safe, well and happy.
Lotsa huggs
Catherine
