I’m guessing “Stop raising, arming and abandoning death squads all over the world for your own purposes” doesn’t make the list. No, when a tatted up nazi shouts “Slava Ukrani” before opening fire on a Russian-American cultural center or something, it’ll be the fault of those damn hispanics.
9/11 probably still focus tests as the most memorable event likely to evoke strong feelings to the average american. My father (who became american later in life) has half his office decked out in 9/11 memorabilia. Don’t even get me started on his truck stickers.
