As it's previously been said, all the topics listed are great topics to look into. I find the first one very interesting as you can discuss not only your own view points surrounding this subject, but you can also include those of others and compare them - you could even compare the opinions of those outside of the the D/deaf community. It's also a good one to compare and provide data and discuss that data, e.g. you could do surveys with it as well! Hope you can figure out what you'd like to do and that it goes well for you! 🙂
