Are you not aware that Australia, Canada, Denmark, the Czech Republic, France, Germany, Greece, Ireland, Italy, The Netherlands, New Zealand, Poland, Portugal, Norway, Spain, Sweden, Switzerland, the U.K, and 50 other countries all supported the invasion of Afghanistan in 2001? Why is it you think none of them have any responsibility aside from the U.S.?
Are you aware that a majority of us Americans were always staunchly opposed to Trump - which is why he's the only President in nearly 3 decades to lose re-election?
Maybe, just maybe, the anecdotal things you read in this forum are from a few wing nuts that don't represent all Americans? As an American, I am appalled by some of the incredibly stupid shit these guys are saying too.
Honestly, I can't imagine hating someone for being born somewhere the way you do. it strikes me as nativist and nationalist - both concepts that are utterly without merit in my view.
