Yeah, those are good analogies. The Thurmond and Byrd ones, not the Lindbergh one. I never understood why people always have to draw parallels in situations and can't just take them as they are. There seems a huge world of difference in causes and motivations between the pre-WW2 isolationalists and the xenophobic tendencies of people towards aliens after the Xindi incident.
I just don't understand how Earth can transition as presented in the show to loudly protesting against aliens, supporting Terra Prime even after they committed terrorist acts and with a Minister of some sort who's likely quietly sympathetic to them even if he won't come out and say it to starting up the Coalition of Planets in the same episode. The only people who stuck up for it were the main cast and Samuels who's literally just hugging the line between the two for political survival.
