Enhancement of human rights in USA during Obama's presidency

My research question is: Were human rights improved during president Obama's period? I'm going to analyze human rights conformability by historical order in USA. It is obvious that, we can't skip the incident on 11 September as well; because this is the most large-scale terrorist attack for the history of America. 9/11 attacks affected not only US, but also whole world. My thesis argument is about development of human rights during the Obama era. Especially, I emphasize LGBT and Immigration rights. My point of view is that the rights of immigrants and trans-genders were improved during Obama's presidency. I conduct historical research; support my argument by facts and the mixed cases as well. To illustrate transgender immigrants and their treatment while they are inside US borders is one of among many. I'll support my argument by comparing presidency periods of other US presidents with Obama. Then I'm going to compare valuable facts about human rights throughout the US history and conclude my argument. As a result in a final stage my goal is to prove correctness of my argument.
