Watergate was such a big scandal that Nixon gave up before the impeachment procedure had even began, and it left such a big mark that we still talk about it so many decades later.

It's been an endless stream of reports of scandal and cruelty since 20161980. How could you not get desensitized? The alternative would be to go insane.
