Well dude, when you hit my age (70s), and as an American, you continue your longstanding tradition of not caring about the background of your friends. After all, in my world, there are two types of folks, Yanks and Not Yanks. Now some of my best friends arent Yanks, but Im ecumenical.
That being said, in this instance, there are two types of people in my world. Folks that stand with the good old USA against terrorism, antisemitism, neo nazism, anti Americanism and those that don't. Remember, this wasnt just an attack on Israel, but an attack on US citizens too
