The author is rightly "puzzled" by Trudeau's statement that he's jealous of immigrants because "immigrants got to choose Canada while those born here were Canadians by default."

Puzzling is right.....right up there with:
1) The budget will balance itself
2) Admiring the Chinese dictatorship because they can "turn on a dime"
3) Growing the economy from the heart out
4) His glowing eulogy that  gushed: "Fidel Castro was the longest serving Cuban President"
