...and really, my first reaction to hearing the thing about Superman renouncing his US citizenship was "Dont let the door hit you in the ass on the way out."
I know some folks were thinking only Fox News fans would have an issue with it, but while I'm not phased in the least by dropping the phrase "...and the American way", renouncing his citizenship is another thing altogether. To me, it sends the message that an American cannot have the greater good of the world in mind... That to do that, one has to distance oneself from this country. That's bullshit. What's more, it strikes me as Superman distancing himself from the country that raised him because it's easier in an age where America is polarizing.
Superman can be American and still differ in opinion from those in charge of the country. That's part of being an American, and standing up and offering an example of that is valuable. But hey, if it's too inconvenient for him, then I understand. I wouldn't want him to strain himself or anything.
